|
the telencephalon (cerebrum) is divided into what three aspects?
|
hemispheres, cerebral cortex, and basal ganglia (deep cerebral nuclei)
|
|
|
the diencephalon (thalamus) is divided into what three aspects?
|
dorsal thalamus, hypothalamus, and subthalamus
|
|
|
what function does the dorsal thalamus have?
|
it is a sensory and motor relay center to the cerebral cortex
|
|
|
in relation to the central sulcus, where is the motor anlyzer located? the sensory analyzer?
|
motor analyzer is anterior to the sulcus while sensory is posterior
|
|
|
what is the role of the primary motor cortex? primary sensory cortex? associative cortex of each?
|
primary motor is where upper motor neurons are located. primary sensory is where sensation comes into consciousness. Associative areas for each is where these things are analyzed
|
|
|
the lateral brain is also known as?
|
the intellectual brain
|
|
|
everything we see is perceived where on the cortex and what is this phenomenon called?
|
perceived on the primary visual cortex locared in the lateral occipital gyri, specefically on the medial side in the area of the cuneus and lingula. This is called retinotopic localization
|
|
|
perceiving hearing is located where on the cortex and what is this called?
|
the primary auditory cortex which is located in the transverse temporal gyri. this is called tonotopic localization
|
|
|
where do we perceive touch and pressure in the cortex, and this localization is called what?
|
in the primary somatosensory cortex AKA the sensory strip located on the postcentral gyrus to the posterior paracentral lobule medially. This is called somatotopic localization
|
|
|
what are the major areas of the sensory homunculus of the primary somatosensory cortex?
|
on the lateral side caudorostrally: face, hand upper limb, and trunk.
on the medial side caudorostrally: external genetalia and lower limb |
|
|
where is the primary motor cortex located?
|
on the precentral gyrus and the anterior half of the paracentral lobule medially
|
|
|
how does the motor homunculus compare to the sensory homunculus in its organization?
|
they are simillar
|
|
|
what is the function of the insular cortex?
|
complex integration of sensory, autonomic, and limbic inputs (sensory analyzer not motor)
|
|
|
what is the flow of information in the cortex when making decisions?
|
sensation arrives in that part of cortex, then the sensory analyzer attacks and sends info to the motor analyzer for analysis and decision making and then to the primary motor cortex for the action
|
|
|
what are other names for the limbic lobe?
|
the medial brain and the emotional brain
|
|
|
the limbic lobe contains what structures?
|
the subcallosal gyrus, subcallosal area, cingulate gyrus, parahippocampal gyrus, uncus, and hippocampus
|
|
|
what are the functions of the hippocapmus?
|
processes short term memory into long term memory
|
|
|
where in the limbic lobe is the hippocampus located?
|
inside the inferior horn of the lateral ventricle
|
|
|
the limbic system is made up of what structures and what is its function?
|
limbic lobe and multiple subcortical areas. functions are instinctive behavioral mechanisms, emotions, and survival mechanisms.
