aka telencephalon, most superior region of CNS. Composed of cerebral cortex, basal ganglia, and limbic system.
involved in smell
provides main motor and sensory innervations to the face and neck via cranial nerves
prominent landmark of brain separating parietal lobe from frontal lobe
Superior temporal gyrus
auditory cortex and sensation of sound
emotion, processing, learning
C-shaped bundle of axons that carries signals from hippocampus to mamillary bodies and septal nuclei.
part of the brain where the optic nerve partially cross
where the primary visual cortex is concentrated
almond-shaped groups of nuclei; primary role is memory of emotional reactions/fear.
long-term memory and spatial navigation
unconscious homeostatic and reflexive pathways
auditory and visual reflexes
relays signals from the forebrain to the cerebellum, deals with sleep, respiration, swallowing,bladder control, eye movement, facial sensation, posture
vital body functions such as breathing and heartrate
produces serotonin derivative melatonine (sleep/wake cycle)
production of acetycholine
mostly myelinated axons
all kinds of axons and capillaries, neural cell bodies as well
regulates movement and learning
planning and inhibition of movements
learning and memory
homeostasis, self awareness, cognitive functioning
reward, addiction, movement
uses x-ray beams (rotating) to generate a brain slice and digitally reconstruct the image
uses info on how hydrogen atoms respond in the brain to perturbations of a strong magnetic field
looking at the relationship between activity in certain brain areas and mental functions, ex: PET, fMRI, EEG, etc.
fMRI & PET
detect changes in blood flow & metabolism in the brain. Since ative neurons have more glucose & oxygen, there is more blood flow there.
Cell bodies in layers, surface layer separated from pia mater, apical dendrites form multiple branches
What are common features of the cortex?
separated from parietal lobe by post-central gyrus. Contains dopamine sensitive areas of cortex associated with reward, attention, long-term memory, planning, and drive.
integrates sensory info ffrom different areas
lobe involved in vision
lobe involved in auditory perception
outer layer of the cerebral hemispheres, made up of six layers labeled I to VI. Is part of the cerebral cortex. Involved in sensory perception, generation of motor commands, spatial reasoning, conscious thought, and language.
top layer of cerebral hemispheres in brain of mammals
Convex fold or elevation in surface of brain
grooves/trenches/fissures in brain
situated in the medial aspect of the cortex, includes cortex of cingulated gyrus, which lies immediately above corpus collosum.
vision (near occipital lobe)
processing and memory of emotional reactions/fear
sensory switchboard of the brain
lower part of forebrain
