Fore, Mid, Hindbrain - Coggle Diagram
Fore, Mid, Hindbrain
Forebrain (prosenchepalon)
cerebral hemispheres (L&R)
outer region is the "cortex". (
Image is NB
)
(Laminae: layers of cell bodies parallel to surface of cortex and separated by layers of fibers)
Frontal Lobe
Function: processes motor info
Parietal Lobe
processes sensory, spatial & also numerical info
Temporal Lobe
Function: hearing & understanding spoken language
Occipital Lobe
processes visual info
Subcortical structures (under cortex)
Thalamus, hypothalamus, pituitary gland
Thalamus: pair of structures (L&R) in center of forebrain. First to receive & process sensory info (except olfaction)
Hypothalamus: small area near base of brain ventral to thalamus. Controls pituitary gland, thus has neural and hormonal influences.
hypothalamic damage leads to abnormalities in motivated behaviors (eating, moving, sleeping, sex)
basal ganglia
consists of globus pallidus, caudate nucleus, putamen
Damage to basal ganglia impairs movements (Huntington's & Parkinson's), as well as learned skills, habits (learning that requires extended experience)
Functions: plays role in movements, (complex) learned motor skills, forming habits
Limbic System (HHAOC)
Olfactory Bulb
Hypothalamus
#
Hippocampus
Critical function in memory, esp. individuals ones like location and direction
amygdala
Function: evaluates emotional info, esp. WRT fear
cingulate gyrus (actually part of cortex)
Basal Forebrain
Nucleus Basalis
Receives input from basal ganglia and hypothalamus to
release acetylcholine
Releases acetylcholine to increase wakefulness & arousal
Ventricles
Cavities filled with cerebrospinal fluid
Hindbrain (rhombencephalon)
Medulla oblongata
controls vital functions ( breathing, heart rate, vomiting, salivation, coughing, and sneezing) via 12 cranial nerves
Pons
Transmits impulses b/w forebrain & cerebellum. Involved in sleep/wake cycle, breathing rhythm (with medulla)
Cerebellum
major role in activities requiring accurate timing (incl. balance and coordination, musical skills)
and shifting between (auditory & visual) stimuli
Midbrain (mesencephalon)
Tectum ("roof")
Superior colliculus
swelling on tectum; processes visual info
inferior colliculus
swelling on tectum; processes auditory info
Tegmentum ("floor covering")
covered by tectum, but it coveres other brain regions
substantia nigra
contains dopamine pathway that gives rise to movement
Brain stem consists of: medulla, pons, midbrain, and certain central structures of the forebrain
