|
Central sulcus: what does it divide? |
Parietal lobe from frontal and primary motor cortex from the somasensory cortex. |
|
|
Lateral sulcus: what does it divide? |
Parietal and frontal from the temporal lobe. |
|
|
Parietooccipital sulcus: what does it divide? |
Medial part divides boundaries between parietal and occipital lobe and cuneus and pre cuneus. |
|
|
Premotor cortex: what is its function? What problems can a lesion in this area cause? |
Activates smaller muscles and works with the premotor, supplementary motor cortex and the posterior parietal to excite movements. Lesions can cause hemiplegia or monoplegia. |
|
|
Prefrontal cortex: what is its function? |
Inferior and medial: personal identity, olfaction and social behaviour - area affected in dementia.
Lateral: intellectual abilities. |
|
|
Paracentral lobule: what are its functions? And what can lesions lead to? |
Motor and sensory innervations of the lower extremity, lesions can lead to lower limb muscle weakness and urinary incontinence. |
|
|
Primary sensory area: what's the function and what can a lesion cause? |
Receives sensations from body wall (pain, temp, vibration etc). Lesion can cause contralateral anaesthesia of the head and upper and lower limb. |
|
|
Superior and inferior parietal association areas: what are the functions and what can lesions in these areas cause? |
Superior: stereognosis
Inferior: interpretation of emotional and sensory stimuli.
Lesion in the superior can cause astereognosis.
Lesion in the inferior can cause neglect syndrome. |
|
|
Corona radiata: what does it contain? |
Ascending and descending axons that carry neural traffic from and to cerebral cortex. |
|
|
Thalamus: what does it do? |
It's involved in sensory perception and regulation of motor functions, sleep and relays sensory information to the cerebral cortex. |
|
|
Hypothalamus: what does it do? |
Homeostasis Autonomic function control Endocrine function control Motor function control Food and water intake regulation Sleep and wake cycle regulation |
|
|
Middle cerebellar peduncle: what fibers does it contain? |
Afferent |
