CEREBRART - Brain Plasticity



What is really "Brain Plasticity"? Does it mean that the Brain is made of organic plastics? Of course,  not. Brain Plasticity is a concept that refers to the Brain's ability to change in time and sometimes chaotically ...

CEREBRART - Fungy Brain

 “The rhythm of life on Earth includes several strong themes contributed by Kingdom Fungi. So why are fungi ignored when theorists ponder the origin of life? I am very sorry to say that I strongly suspect it is simply a display of ignorance.“ (David Moore) And why are fungi ignored when theorists ponder the evolution of the brain? The human brain is essentially fungy because it is funny and also reveals the importance of Kingdom Fungi in human brain evolution. Perhaps that is why humans love, and pre-humans needed to eat some fungi so much. According to my point of view,  the origin and detailed structure of the mammalian brain depends on the dominance of fungi in the Earth’s biosphere. Various fungi with hallucinogenic properties are the oldest drugs to be used for its effects on the human brain. These drugs have long been an important part of religious ritual in many societies where their potential for chaos generation is also recognised. And human agriculture is also dependent on fungi. “That’s why I suggest it’s fair to say that fungi co-operate with humans … they waited nearly 1.5 billion years to give human evolution a shove in the right direction. Thank fungus for that!“ (David Moore) This CEREBRART work illustrates these ideas.

CEREBRART - Between the Sky and the See

Somewhere between the Sky and the See there are three cone pigments in the human retina which absorb Light maximally in the red, green and blue regions of the Sun’s spectrum and provide colourful information flows about the World for the Brain. And there are dark lines within the Sun’s spectrum and there are rods in the human retina which mediate human vision in the darkness. And the Light shines on in the darkness, and the darkness has never put it out.

EDIBLE CEREBRAL ART


It' s pretty self explanatory. This brainy stuff is not CEREBRART but looks delicious.

CEREBRART – INTENTIONAL CHAOS


Schizophrenia is a mental illness that seriously affects intentions. People with schizophrenia have difficulty in creating own and interpreting others' intentions. Human actions can occur in response to externally acquired information and/or as a result of internal volition based on internal motivation. A central monitoring brain system distinguishes between  the two when actions are made creating the sense that a person’s action is the consequence of his or her intention.  In schizophrenia, there is a deficit in this central monitoring brain system such that actions from willed intentions are mistaken as being derived from external informational sources. There is evidence towards cortical hyperexcitability in schizophrenics (glutamate chaos in the brain) because of a lack of inhibition as a background related to the anomalous manner to process information and inability to infer intentions behind pieces of information. This intentional chaos produces the belief that one’s actions are caused by others, that certain thing have intentional significance for the person and to attribute negative intentions to others. In schizophrenia, one may feel compelled to act even against one’s conscious intentions. This CEREBRART work explains these ideas artistically.

CEREBRART - Aggressive Brain


Aggression has become an important cultural problem worldwide presumably because of its deep seeded evolutionary roots in the neurochemical pathways and neuronal circuits of the human brain. Functional brain imaging studies in humans have revealed involvement of specific regions in the brain
in the expression of aggression and rage and chaotic neuronal circuits that play particularly important roles in the mechanism of aggression. Main general causes of aggression in people with neurodegenerative conditions are the frustration and anger associated with the person’s awareness of their predicament, and the structural brain damage and neurochemical alterations caused by damage and death of brain cells which automatically motivates aggression. In some psychopathic individuals the extremely heightened aggression was possibly the result of a selective decrease in brain serotonin turnover and a probable deficiency in the 5-HT1A or 5-HT1B receptor in brain regions regulating aggression which motivates those individuals to aggress. This CEREBRART work illustrates these ideas.

CEREBRART - Prosopagnosia

Prosopagnosia is a disorder of face perception where the ability to recognize familiar faces (such as their immediate family members) is impaired, although the ability to recognize other objects may be relatively intact. Further, some impairments in recognizing facial expressions have been reported in a variety of diseases like Huntington’s disease, Parkinson’s disease, Alzheimer’s disease and schizophrenia. I think that prosopagnosia and related disorders are caused by jumping between different chaotic attractors in the primate brain networks. The primate face is evolved evolutionary to be a beautiful attractor for the primate brain networks in a turbulent world of chaotic forest ecosystems representing important attributes such as attractiveness or social status. I think that a normal primate brain is able to represent the known faces as attractors of the neural network. Normally, the primate brains gather visual information through the eyes and the primary visual cortex and modify dynamically specific facial muscles to be interpreted properly by other primate brains through nonlinear feedback processes of iteration and mutual communication. Inability to stabilize such complex nonlinear feedback processes may suggest the emergence of chaotic attractors in the brain networks. This CEREBRART work illustrates these ideas artistically.
P.S. According to a recent comment I tried to generate a primary artistic design idea for an artefactual facial attractor to help people with Prosopagnosia ...

CEREBRART - Dorsal Anterior Cingulate Cortex

Many studies have provided evidence that social conflicts can generate activation in the Anterior Cingulate Cortex. The Anterior Cingulate Cortex is the frontal part of the Cingulate Cortex, that resembles a collar around the brain corpus callosum.

This CEREBRART work  illustrates the Dorsal Anterior Cingulate Cortex that is  involved in the distressing experience of social exclusion and might represent a circuit that underpins sadness.  So, this partially isolated brain illustrates not only an increased activity in the Dorsal Anterior Cingulate Cortex but also as an abstract idea of the experience of distress following social rejection/isolation associated with greater activity in the Dorsal Anterior Cingulate Cortex.

CEREBRART - Basket Cell

Despite more than 100 years of scientific research, the causes of schizophrenia are still unknown. Neural oscillations are a fundamental mechanism for enabling coordinated activity of brain cells.

Recent evidence from electrophysiological, physiological and anatomical studies suggests that abnormalities in the oscillatory activity of brain cells may have a central role in the pathophysiology of schizophrenia. There is evidence towards cortical hyperexcitability in schizophrenics - “Glutamate Chaos” because of a lack of inhibition. 

Dysfunctional oscillations may arise owing to anomalies in the brain’s rhythm-generating networks of GABA-interneurons.

Of the GABA-interneurons types, the cortical Basket Cells are very characteristic in that their axons, when viewed under the microscope, terminate on somata and proximal dendrites of Pyramidal Cells. Therefore, Basket Cells, whose axon terminals surround principal cell somata and proximal dendrites, have a privileged and influential position for regulating the firing of Pyramidal Cells.

The strategic location of Basket Cells axons has long suggested that they subserve inhibitory
mechanisms on the somata of Pyramidal Cells possibly preventing and limiting chaotic processes - “Glutamate Chaos” - in the network of Pyramidal Cells. Thus, altered perisomatic inhibition of Pyramidal Cells by Basket Cells could provide a plausible mechanistic basis for the gamma-oscillation impairments and cognitive deficits in schizophrenia. In the future, this hypothesis may provide a powerful research tool to gain new insights on ways to limit chaotic processes and restore gamma oscillations in schizophrenia.

This CEREBRART work illustrates these ideas artistically.

CEREBRART - MONDRIAN AMACRINE

This CEREBRART work is a mondrianesque transformation of my original painting of the retina approximately symbolising  the cellular transformation that accompany the transmission
of light signals.  I have retained the basic organization of the original painting.

As you probably know, +Piet Mondrian was a sophisticated intellectual and Mondrian’s artistic genius focussed on his search for an underlying structure of nature lay in his unique arrangement of the pattern elements, one that causes a profound aesthetic order to emerge triumphantly from stark simplicity.

This CEREBRART work consists of just three basic colors (approximately symbolising three kinds of retina cone photoreceptors cells), a few black lines (as an artistic scaffold approximately symbolising the glial scaffold of retina) and an otherwise uneventful background of plain white (approximately symbolising the white light to be transformed by the retina). Only one amacrine cell is still left to be presented rather realistically. Amacrine cells provide a mechanism for lateral signal communication between retinal cells, including providing a feedback loop to bipolar cells. They are assumed to play an important role in object segregation including perception of +Mondrian’s paintings.

CEREBRART - REFLECTING THE ACTIONS



The real (non-chaotic) perception of time by the human brain is the consciousness of the succession of physical actions (oriented to success or oriented to reaching understanding) and cognitive reflections on a sequence of one’s actions that have already taken place, upon the consequences of those actions and feelings of pain or pleasure in response. Already in 1871 Darwin wrote in his “The descent of man” that moral beings must be capable of reflecting over and evaluating their actions. Ideally, all human actions should be evaluated by reflecting upon specific principles, using this reflective process to rationally deduce a specific judgment and to improve the person’s capacity for subsequent performances. But in reality the filters that our brain applies are rather chaotic and highly influenced by multiple external factors. Therefore, when our brain creates anything, it also creates chaotically other things which are not what we intended. Only time will tell if our reflections are valid or not as it will become clear what has and has not worked. There is, of course, no way of asking non-human beings to reflect of their actions, but humans can be asked. CORRECTION: It seems that corvids, carrion crows (Corvus corone corone) and ravens (Corvus corax) could reflect as well.Photo Joachim S. Müller's photostream http://www.flickr.com/photos/joachim_s_mueller/ And now it is clear that the medial frontal cortex of the human brain is crucially involved in self-generated action and post-actional self-reflection but it remains to be shown why it is that self-reflection depends on mechanisms on the medial frontal surface and which other parts of the brain are involved in post-actional self-reflection. This CEREBRART work illustrates these ideas.

CEREBRART - INFORMATIONAL CHAOS

This CEREBRART work illustrates informational chaos in the brain. No motivation. No intention. No volition. No action. No reflection. No integration. Nothing else here, just pure information, chaotic, harsh and uncompromising.

CEREBRART - My February Tribute to Boris Pasternak



Boris Pasternak (born on 10 February 1890 and died of lung cancer on 30 May 1960 filled with pain and suffering) is widely regarded as the greatest of the Russian philosophical lyric poets. During my school years I was deeply influenced and inspired by his poetic world laden with profound and complex imagery and I have even attempted to create a portrait of Boris Pasternak on the glass plate.


This CEREBRART work attempts to illustrate some of his philosophical thoughts. An approximate translation of just one great excerpt would sound like:

…But older age is Rome, demanding
From actors not a gaudy blend
Of props and reading, but in earnest
A tragedy, with tragic end.

A slave is sent to the arena
When feeling has produced a line.
Then breathing soil and fate take over
And art has done and must resign.

CEREBRART - Nucleus Accumbens

The nucleus accumbens (there are two symmetrical nuclei accumbentes in the human brain) which has been described as an interface between limbic and motor brain systems is the "pleasure center" of the brain selectively activated during the perception of pleasant, emotionally arousing pictures (like this one) and during mental imagery of nice people, laughter and pleasant, emotional scenes. Through still poorly understood mechanisms dopaminergic input from the ventral tegmental area regulates the activity of neurons within the nucleus accumbens. The output neurons of the nucleus accumbens send axon projections to the ventral pallidum which, in turn, projects to the thalamus, which projects to the brain cortex. This CEREBRART work illustrates the neural basis of pleasure and perhaps the visitors of my CEREBRART blog will have the additional pleasure of enjoying this picture and activating their own nuclei accumbentes.

CEREBRART - HUNTINGTON’S DISEASE

Huntington’s disease or Huntington’s chorea, from the Greek word for “dance” is the most common genetic cause of chaotic involuntary movements.  Neuropathologically, Huntington’s disease is characterized by atrophy of the heads of the caudate nuclei and enlargement of the frontal horns of the lateral ventricles. This CEREBRART work is presented without providing any further detailed explanation of the damaged cellular, tissue and organ structures shown here, and thus becomes a means for the spectator’s imaginations and neurobiology knowledge applications.
