Lecture 8 - Lena Flashcards
Define Sulcus
little dips and grooves that increase our brains surface area allowing more brain to be packed in our head
What is the biggest Sulcus in our body
Longitudinal Suclus
how is our brain organized
contraleterally
do our left and right hemisphere function independently?
No
Define Corpus Callosum and its function
a handful of neurons that go from one hemisphere to the next
allows left and right hemisphere to communicate
Which side of the brain allows us to produce speech and understand speech
left
What are the 3 different areas of the brain
Hindbrain, Midbrain, Forebrain
What is the Hindbrain responsible for
automatic processes (ex; blinking, breathing, heart beat, balancing, walking, riding a bike)
What is the midbrain responsible for
making neurotransimitter
what is the forebrain responsible for
ability to think, listen, hope, feel, learn
Were is the cerebellum found
Hindbrain
What is the cerebellum in control of
Fine Motor Movements (balance, walking, running, riding a bike)
Were do the singals for fine motor movement origanate
Forebrain
Where are fine motor movements refined
cerebellum
where is the reticular formation located
hindbrain
what is the reticular formation in charge of
how alert you are
Where is the medulla located
hindbrain
What is the medulla in charge of
automatic processes (heart beating, breathing, blood circulation)
Where are pons located
hindbrain
what do pons do
relays information from cerebellum to rest of brain
Were is Substina Nigra located
Mid brain
What does Substina Nigra do
makes dopamine
Where is ventral tegmental area located
Mid brain
what does ventral tegmental do
Produce dopamine
Where is Raphe Nuclei located
Mid brain
What does Raphe Nuclei do
makes serotonin
Where is Locus Coeruleus located
Mid brain
What does Locus Coeruleus do
makes norapinephrine
what is the frontal lobe made up of
4 lobes and subcortical stuctures that are just underneath the cortex
What is the frontal lobe in charge of
Executive functioning (concentrating, thinking, sitting, making judgments)
