Plastizität


A. H.
Diese Lernkartei behandelt das Thema Neuroplastizität auf Universitätsniveau und beleuchtet die Anpassungsfähigkeit des Gehirns. Sie konzentriert sich auf Veränderungen im grauen und weißen Gehirnvolumen, insbesondere im Cortex und anderen Hirnregionen, durch verschiedene Aktivitäten und Berufe. Professionelle Musiker, Golfer, Pianisten und Mathematiker zeigen spezifische Anpassungen in ihren Gehirnstrukturen. Die Karteikarten sind nützlich für Studierende der Psychologie, die verstehen möchten, wie Training und Berufserfahrung die Gehirnstruktur beeinflussen.

Cartes-fiches

Xenomelie

Show reduced cortical surface area in

-the primary+ secondary somatosensory cortices

-inferior parietal lobe

And reduced cortical thickness in the superior parietal lobe

 

Professional pianists

Primary and secondary motor areas (M1, SMA, pre-SMA, CMA) were to a much lesser degree activated in professionaö pianists (strongest for the pre-SMA + CMA)

"Weniger aktivität in mesiofrontalen hirnbereichen bei Pianisten während bimanualem Tapen"

 

 

 

Modulation von Assoziationen (visuell-auditorisch) (Jäncke et al., 2004)

-no activation in primary auditory cortex during imagination

-activatioin planum temporaöe and superior temporal gyrus

3 monatiges Lernen fürs Physikum

Zunahme der Dichte der grauen Substanz in parietalen Strukturen (right posterior and lateral parietal cortex) und im Hippocampus (left hippocampus)

Extremity amputees (draganski, 2006)

Decreased GM in the posterolateral ventral nucleus of the thalamus controlateral (dort wo Bahnen umgeleitet werden zum S1)

Restless legs syndrome

Increased GM density in the thalamus bilaterally

 

Mathematicians

Increased GM volume in the right inferior parietal cortex and positive correlation with the time spent as mathematicians

Professional golfers

- Increased GM volume in the parietal and premotor cortex

- decreased WM volume in the right corticospinal tract and left external capsule

 

-decreased FA in both corticospinal tracts and both internal capsule

Visuospatial cognition

Female: positive correlation with parietal GM volume

Male: positive correlation with parietal WM volume

Kleine Gehirne

Mehr GM

Gaussian classifier array: spatial information used in classification

1. Number of possible anatomical classes at a given global position is small

2. Neuroanatomical structures occur in a characteristic spatial pattern relative to one another (amy is located anterior to hippoc.)

3. Tissue classes have spatially heterogeneous MRI properties that vary in a spatially predictable fashion

Grapheme-colour synaesthets

Increased cortical volume, thickness and surface are in the

-fusiform

-lingual and calcarine cortex

Inferior fronto-occipital fascicle

Frontal-external capsule-parietal-occipital

Superior fronto-occipital fascicle

Frontal-parietal-internal capsule

Inferior longitudinal fascicle

Temporal pole-occipital pole

Superior longitudinal fascicle

Insular pole- Broca-wernicke-temporal

Uncinate fascicle

Orbitofrontal -temporal

Professional musicians

Lower FA of the corticospinal tracts in musicians compared with controls (links, der die dominante Hand steuert)

Juggling 3 month

Bilateral gray matter expansion in the medial temporal visual area (v5)

-extent reduced after 3mt without juggling

-left posterior intraparietal sulcus increased

Juggling 7 days

-increased GM in V5

-changes were larger in initial learning phase than during continued learning

2 hours training on a spatial navigation task (Sagi, 2012) 

-reduction in mean diffusity in the left hippocampus, and left and right parahippocampus

-increase in FA in the left parahippocampus, right supramarginal/angular cortex, right superior temporal gyrus, right amygdala- left pulvinar
