Unit 3.5 - The Limbic System Flashcards
What is the corpus colosseum?
It is connective tissue that connects the right and left side of the brain.
What are the left and right myths?
Artistic vs. Analytical
Intuitive vs. Logical
Different personailities
What is the contralateral effect?
In most people, the right hemisphere controls the left side of the body while the left hemisphere controls the right side of the body. Thus there is such things as dominant hand, foot, and age.
How are right-handed people with language?
They process language in the left hemisphere.
What are left-handed people with language?
They have more diversity in language processing and brain is unique, may use both hemispheres.
What is callasotomy?
It is the split brain effects, both sides work independently. Left eye = left field of vision but saw square which was on right eye vision.
Right eye = right field of vision but saw circle which was on left eye vision.
Can’t say what is on the left eye because because of specialization of language is on the left side of brain, left hemisphere has no access to what left eye sees, only right hemisphere sees.
What do the ventricles and meninges do?
They hold cerebrospinal fluid which support and cushion brain.
What is in the limbic system? It is involved in behavioural and emotional responses.
The thalamus, hippocampus, hypothalamus, amygdala, basal ganglia, and parts of the brain stem.
What does the thalamus do?
The thalamus is a sensory relay station, senses channel through thalamus before going to special parts in cerebrum. DOES NOT INCLUDE OLFACTORY BULBS.
What does the hippocampus do?
It is responsible for the formation fo short-term memories, it retrieves and constructs new ones. It faces neurogenesis throughout life.
What does the hypothalamus do?
It is below the thalamus, it is the connection to the endocrine system as it produces hormones, regulates temp, BP, and appetite.
What does the amygdala do?
It is the the fear centre, and it is responsible for panic and emotional reactions and emotional memories. The bigger it is the more emotional the person.
What does the basal ganglia do?
It is for pleasure and novelty and surprise.
What is in the brain stem area?
Medulla, pons, cerebellum, spinal cord.
What does the pons do?
It is the bridge between the hindbrain and forebrain. It is responsible for autonomic processes during sleep like movement of eyes and sleeping transitions.
