3 main components of Basal Nuclei |
- caudate nucleus - globus pallidus - putamen |
|
Basal Ganglia Function |
-regulates muscle tone -voluntary movement, motor planning, initiation of movement |
|
What is the Limbic system responsible for? |
Emotional- instinctive - visceral functions (anxiety, fear, rage, reward, sexuality) |
|
What is apart of the limbic lobe? |
Cingulate Gyrus Subcallosal Gyrus Isthmus Parahippocampal Gyrus Uncus |
|
Amygdala |
Almond shaped mass deep within the medial temporal lobes, lateral to the hypothalamus and above the hippocampus |
|
amygdala functions: |
Fight or Flight Emotional response Emotional Learning/Memory Sexual Behavior |
|
Fornix |
Arching band of nerve fibers that connects the hippocampus to the mammillary bodies of the hypothalamus and forms an arch over the thalamus |
|
Hippocampus |
Consolidation of new memories (converting short term memory to more permanent memory) and retrieval of memories Navigation in spatial orientation (spatial relationships) Emotions (esp. emotional memory) |
|
Diencephalon is composed of: |
Thalamus Hypothalamus Epithalamus Subthalamus |
|
Thalamus: |
Largest structure in diencephalon Very important for speech, language and hearing. Serves as a major relay station Nearly all sensory input is processed in this. |
|
thalamus function: |
Relaying, sensory and motor signals to the cerebral cortex, regulation of consciousness, sleep, and alertness |
|
Hypothalamus |
Ventral most portion of diencephalon Central integrating nuclei for both sensory and motor control of our viscera (internal organs) Controls much of hormonal (endocrine) system with connection to the pituitary gland Strong, functional and structural relationship to limbic system (EMOTIONS) |
|
Epithalamus |
Composed of paired tracts, a pair of nuclei, and a midline structure Regulates circadian rhythmic information Pineal body is more like a gland than nervous system structure |
