- Hindbrain
-
1. Medulla
2. Pons
3. Cerebellum - Hindbrain Functions
- Balance, Posture, Coordination
- Midbrain
-
Reticular Activating System
(RAS) - Midbrain Functions
- Consciousness, Arousal, Wakefulness
-
Forebrain
(Cortical and Subcortical Structures) -
1. Thalamus
2. Hypothalamus
3. Basal Ganglia
3. Limbic System -
Thalamus Functions
(Forebrain) - Relay station for all sensory input except Olfaction
-
Hypothalamus Functions
(Forebrain) -
1. responsible for vital functions of hunger, thirst and temperature regulation
2. Integrates responses needed to maintain internal homeostasis
3. SCN mediates sleep-wake cycle - Suprachiasmatic Nucleus (SCN)
- located in hypothalamus. mediates sleep-wake cycle. SCN involved in Seasonal Affective Disorder
- SAD
- Seasonal Affective Disorder-Suprachiasmatic Nucleus (SCN) seems involved.
-
Basal Ganglia Functions
(Forebrain) -
plan, organize, and coordinate bodily movement
involved in motor movement symptoms of Huntington's and Parkinson's
also involved in expression of emotional states (smiling when happy, running when scared) -
Basal Ganglia Structures
(Forebrain) -
1. Caudate Nucleus
2. Putamen
3. Globus pallidus
4. Substantia Nigra -
Limbic System Functions
(Forebrain) - Primarily associated with the mediation of emotion
-
Limbic System
(Forebrain) -
1. Amygdala
2. Hippocampus -
Amydala
(Forebrain, Limbic System) -
1. attaches emotions to memories
2. integrates and directs motivational and emotional activities
3. involved in recall of emotionally-charged experiences
Bilateral lesions in Amygdala and temporal lobes can produce Kluver-Bucy Syndrome -
Hippocampus
(Forebrain, Limbic System) -
1. associated with learning and memory.
2. involved with processing visual, spatial, and verbal information.
3. consolidates declarative memories - Kluver-Bucy Syndrome
- increased docility, hypersexuality, alterations in diet, psychic blindness caused by bilateral lesions in the Amygdala of the Limbic System.
- Psychic Blindness
- Inability to recognize significance or meaning of events or objects. Associated with bilateral lesions of Amygdala of the Limbic System.
- Declarative Memories
-
Converting short-term memories to long-term. (I do declare this short is a long)
Function of the Hippocampus of the Limbic System (Forebrain)
