Experiences and how they make us feel about people, places, certain events in our lives. For example, those who travel as 20 somethings claim to come back home more mature, more rounded and more humble than they left. This is experience driven plasticity taking place. Its fascinating!

I have just created a goup called Psychoplasticity.

I think we need to discuss the borders of neuropsychology and psychophysiology. despite the fact that borders move when new reaerch
demand it

I don't know English, but I like neuropsychology. Pleas, join me.

I’m pleased to join me with the neuropsychology group.
I hope this could be a pleasant way to discus several aspects of human and clinical neuropsychology

DrBotond Roska (Basel Switzerland) et al have made some really exciting research how the eyes can sense without involving neocotex. The article can be found in Nature neuroscience 6 sep 2009
The form of sense they have proved in the eye may function as alarmaystem before the brain react

Hi Istvan Bokkon!
I think that your topics has nothing to do with neurospsychology. There are som other diciplines in neurosience like psychophysiology or psychophysics
where people discuss such things as you do. Best regard Bo

It was proposed that the brain can work passing through pictures, and the properties of homeotherm state make the development of explicit memory possible in our brain (Bókkon 2003, 2005, 2006). That is to say, external electromagnetic visible photons are converted into electrical signals in the retina and then they are conveyed to the V1. These retinotopic electrical signals (spike-related electrical signals along classical axonal-dendritic pathways) can be converted into synchronized bioluminescent photonic signals (inside the neurons) by neurocellular radical reactions (redox process) in retinotopically organized V1 mitochondrial cytochrome oxidase-rich visual areas. Then bioluminescent photonic signals (inside the neurons) by neurocellular redox/radical reactions in synchronized V1 neurons make it possible to produce computational biophysical pictures during visual perception and imagery. Our suggested hypothesis is in line with the functional roles of reactive oxygen and nitrogen species in living cells that is not a random process, but rather a strict mechanism used in signaling pathways.
It was also raised that phosphenes are intrinsic perception of induced photon emissions (e. g. via external electric or magnetic fields, etc.) or spontaneous enhanced bioluminescent photon emissions in cells in various parts of the visual system (Bókkon, 2008, Bókkon and Vimal, 2009).
Recently, our prediction (Bókkon 2008) about retinal phosphenes was experimentally verified by Narici et al. (2009) during space travel. According to Narici et al. (2009), phosphene perception in space travel possible due to the ionizing radiation induced free radical processes. That is, these ionizing radiation (cosmic particles) induced free radicals generate chemiluminescent photons from lipid peroxidation, which are absorbed by the photoreceptor chromophores, modify the rhodopsin molecules (bleaching) and start the photo-transduction cascade resulting in the perception of phosphene lights. Besides, it was shown that radicals from lipid peroxidation of the photoreceptors (rods) outer segments of the retina can generate (bio)chemiluminescent photons (bioluminescence is a type of chemiluminescence, which naturally occurs in living organisms) in the visual spectrum.
However, the retinal phosphenes and the cortical phosphenes have to have common mechanism.
If it can be proved that perception of cortical phosphene lights is due to biophotons, intrinsic regulated biophotons in the brain can serve as a natural biophysical (redox molecular) substrate of visual perception and imagery.

concerning human drives there a lot of possibilities to modify their effect i both negative and positive ways during learning and experiences. If this not is enough will the right treatment at first be medical, but we have to wait on the right medicine to do so.

comment to Bokkon.
I dont think it is possible to prove that we have an intrinsic picture emerged on intracellular phenomena in the visual cortex. The brain is very rich in proteinsynteses when we sleep and perhaps also in psychotic patients, and of course the visual cortex may be very active in metabolism during the day. Such things explain very active metabolism in visual cells. I still think that to sense is to reflect the world into the relations between cells involved in sense, but your theory is very interesting and exiting and may bring us to move som steps forward in the research of the visual cortex
