Question 9

In the visual system the various features of the visual information – like colour, luminance, form, motion, binocular information - are processed and analysed in various compartments parallel with each other, from the retina through the lateral geniculate to the visual cortex.

synesthesia

Question 30

With the help of modern neuroimaging technologies a wide network activity in the human brain has been revealed. The internal operations in the brain are practically ceaseless, even during sleep. If the brain is not engaged with a task, information processing is still going on via a network called the _____________ is active or DMN. When a salient stimulus is reaching the senses, a ____________ is activated, alarming the relevant brain regions. During various sensory or motor actions a _______________ network is activated.

Due to the fact that the brain’s global cerebral blood flow cannot change because of anatomical-physiological limitations, the brain should rely on a constant 50 ml/100g/min blood flow. For this reason, neuronal populations the activity of which is not needed during a neuronal operation will receive less regional blood flow and those populations which are active will receive more. This results in a constant redistribution of blood in the brain between active and non-active neuronal populations. This is the basis of functional imaging techniques like CBF-PET, fNIRS, fMRI.

Answer 30

default mode network;

salient network;

central executive;
