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.

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.
