Q

Hippocampus and learning

A

Hippocampus is central to learning and the formation of memories.
People with bilateral hippocampal damage have immediate (sensory) memory (seconds in length) and intact long-term memory (from time before damage) but are unable to form new long-term memories.
Their reflexive memory (motor skills) remains intact

Q

Immediate or Sensory memory

A

a few seconds. Describes the ability to hold experiences in the mind for a few seconds. Based on different sensory modalities. Visual memories decay fastest (<1s), auditory ones slowest (<4s).

Q

Short-term memory

A

seconds to hours. Often called Working Memory. Brain’s “post-it note”. Used for short term tasks such as dialling a phone number, mental arithmetic, reading a sentence. Associated with reverberating circuits.

Q

Intermediate long-term memory

A

hours to weeks e.g. what you did last weekend. Associated with chemical adaptation at the presynaptic terminal.

Q

Long-term memory

A

can be lifelong. e.g. where you grew up and your childhood friends. Associated with structural changes in synaptic connections.

Q

ventricular system is formed by

A

lumen of neural tube

17
Q

Primary brain vesicles

A

Prosencephalon (forebrain), Mesencephalon (midbrain), Rhombencephalon (hindbrain).

18
Q

Secondary brain vesicles

A

Telencephalon & Diencephalon (from forebrain). Mesencephalon. Metencephalon & Myelencephalon (from hindbrain)

19
Q

telencephalon

A

cerebral hemispheres, hippocampus, basal ganglia

20
Q

Diencephalon

A

thalamus, hypothalamus, pituitary gland, pineal

21
Q

Mesencephalon (midbrain)

A

superior and inferior colliculi

22
Q

metencephalon

A

cerebellum, pons

23
Q

myelencephalon

24
Q

what cells line the ventricles

A

Ependymal cells - they have cilia and help move the CSF through the system

25
function of cerebellum
coordinate muscle movements, maintain posture, and balance
26
function of frontal lobe
associated with executive functions including self-control, planning, reasoning, memory storage and abstract thought
27
occipital lobe
vision
28
temporal lobe
audition and language
29
hypothalamus
TAN HATS - Thirst and water balance - Adenohypophysis control - Neurohypophysis releases hormones from hypothalamus - Hunger - Autonomic regulation - Temperature regulation - Sexual urges
30
midbrain
conciousness, processing visual and auditory data, generation of reflexive somatic motor response
31
pons
involved in the control of breathing, communication between different parts of the brain, and sensations such as hearing, taste, and balance
32
medulla
helps regulate breathing, heart and blood vessel function, digestion, sneezing, and swallowing
33
cerebellum
coordinates complex somatic motor patterns. cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity
