Lecture #8, Exam 2 Flashcards
The hypothalamus and the pituitary body make up the…
infundibulum.
the parahippocampal gyrus and uncus are responsible for…
declarative memory (episodic and semantic)
The entorhinal cortex plays a role in…
olfaction.
The orbitofrontal lobe is important for
personality and emotion.
What is Wernicke-Korsakoff Syndrome?
hemorrhaging mamillary bodies which causes ataxia which is remitted, then retrograde amnesia. Caused by a B1 deficiency and is mostly today seen in chronic alcohol abusers. It is temporally graded retrograde amnesia.
the cerebral crura is connected…
to the primary motor cortex and connects to the spinal cord to make synapses on nerves that innervate muscle.
The point where the nerves cross in the medulla is called…
the Pyramids of Medulla (or decussation point)
List the structure involved in the path of upper motor neurons.
to lower motor neurons, to the cerebellum, to the corona radiata, the centrum semiovale, internal capsule, to the corpus callosum, to the pons, decussation, then opposite side. (LOOK UP IF TIME.)
What is the calcarine fissure responsible for, and what are its alternate names?
Primary visual Cortex, Area 17 (Bro). It is responsible for retinotopic mapping. Central vision is medial, peripheral vision is lateral, and the lower half is actually the upper half and the upper half is the lower half like some weird wonderland crap.
The cingulate gyrus is involved in…
social function and anxiety. It is involved but not entirely responsible for social comprehension, or the ability to discern the thoughts and motivations of others.
the cingulate gyrus is involved in what common disorder?
OCD.
Describe OCD.
anxiety provoking, intrusive, recurrent thought. Compulsion refers to behaviors designed to reduce anxiety that are often repeated. There are often themes, including safety, healthy and categories. It can be mild to severe and is treatment with pharmacology, cognitive behavioral therapy and surgery to destroy cells with anxiety as a last resort.
What is cut in split-brain surgery?
the corpus callosum
the other two commissures are called:
the anterior commissure (olfactory) and the posterior commissure which is c-shaped and lower than expected.
The part of the Thalamus that is connected in some humans is called what?
the massa intermedia.
