pre- central gyrus
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. In higher visual cortical areas the information analysis is further specialised alongside the dorsal and ventral processing streams: the “where” information is analysed in the _______________ whereas the “what” information is analysed in the _____________________ pathway, before a unified visual percept is arising as a concerted action in the widely distributed visual network.
dorsal (occipito-parietal) pathway;
ventral (occipito-temporal)
The auditory information is processed from the inner ear auditory apparatus through the ______________ s to the primary and higher level auditory cortical areas.
medial geniculate nucleu
In ____________ due to uncommon anatomical connections between various cortical sensory areas there is a “mixing of the senses” and the subjects may experience perception in other sensory modality domains than the one of the stimulation.
Visual-auditory synesthetes see colours when they hear certain pitches; taste-word synesthetes feel certain tastes when hear certain words, and so on (grapheme-colour, auditory-tactile, etc).
synesthesia
If the external object is accurately perceived but not recognised, it is _____________
associative agnosia.
If the external object is not perceived properly and for this reason it is not recognised, it is ___________
apperceptive agnosia.
What are lesions to the frontal association cortex associated with?
- cognitive: behavioural changes
- language: aphasias
- personality changes
- emotional changes
- movement execution changes
What are lesions to the parietal association cortex associated with?
COntralateral neglect syndrome, Balint syndrome, Gerstmann syndrome, sensory deficits, apraxia
What are lesions to temporal association cortex associated with?
visual agnosias (apperceptive, associative etc);
Auditory agnosia, word agnosia, word deafness
reactive aphasia
dyslexia
What are the functions of the frontal cortex?
These functions are involving action initiation and planning, preparation for movement and movement execution, attention, working memory, emotional regulation, effort regulation, self monitoring.
Brain development, including brain maturation and ageing, is a life-long process. The development and maturation of nervous tissue is not finalised in intrauterine life but continues after birth. Grey matter generation, synaptic density changes (primarily via pruning) - synaptic plasticity, myelination are continuing until_______________ . Learning, practice and skill learning can contribute to structural changes in the cortex: for instance, professional instrument players (pianists, violinists) can have thicker cortex in the planum parietale. After late adolescence the volume of the brain is gradually diminishing, primarily at the expense of the _____________.
late adolescence;
grey matter
Global reasoning capacity, Ability to learn new things, Abstract reasoning, Problem solving, Mental quickness is referred to as ____________ intelligence
fluid
learning from experience, it is fact and experience, culture and education based, it increases with learning and age. is referred to ____________ intelligence
crystallised
What are the key anatomical elements for sleep + circadian rhythm?
retina, hypothalamus, pineal gland, suprachiasmatic nucleus (SCN), paraventricular nucleus
what is the key biochemical component for sleep?
melatonin
What parts of the brain are inactivated during REM sleep?
dorsolateral prefrontal cortex, posterior cingulate cortex
What parts of the brain are activated during REM sleep?
anterior cingulate cortex, amygdala, parahipoccampal gyrus
