Q

What happens when the hippocampus is damaged

A

Can cause damage to memory

situated on or toward the upper side of the body, equivalent to the back

18
Q

Ventral

A

the front, or lower side

19
Q

Anterior

A

the front or direction toward the front of the body

20
Q

Posterior

A

the back or direction toward the back of the body.

21
Q

Superior

A

toward the head end of the body; upper

22
Q

Inferior

A

or caudal - away from the head; lower

23
Q

Lateral

A

toward the midline of the body

24
Q

Medial

25
Q

Forebrain

A

the anterior part of the brain, including the cerebral hemispheres, the thalamus, and the hypothalamus.

26
Q

Midbrain

A

Part of the brainstem
the forward-most portion of the brainstem and is associated with vision, hearing, motor control, sleep and wakefulness, arousal (alertness), and temperature regulation

27
Q

Hindbrain

A

the lower part of the brainstem, comprising the cerebellum, pons, and medulla oblongata

28
Q

Limbic system

A

a set of structures in the brain that deal with emotions and memory. It regulates autonomic or endocrine function in response to emotional stimuli and also is involved in reinforcing behavior

29
Q

Pituitary Gland

A

plays a major role in regulating vital body functions and general wellbeing. It is referred to as the body’s ‘master gland’ because it controls the activity of most other hormone-secreting glands

Nucleus accumbens

A

a region in the basal forebrain rostral to the preoptic area of the hypothalamus

32
Q

Ventral Tegmental Area

A

a group of neurons located close to the midline on the floor of the midbrain.

33
Q

Substantia Nigra

A

a basal ganglia structure located in the midbrain that plays an important role in reward and movement

34
Q

Reticular Formation

A

a set of interconnected nuclei that are located throughout the brainstem
