Rochet CNS Disorders Flashcards
What is found within the Hindbrain?
- Medulla
- Pons, Cerebellum
What is found within the Midbrain?
- Substantia Nigra [SN]
What is Found within the Forebrain?
- Cerebral Cortex
- Basal Ganglia [except SN]: Striatum, Globus Pallidus, Subthalamic Nucleus
- Hippocampus, Amygdala
- Thalamus, Hypothalamus
What is the function of the Medulla within the Hindbrain?
- Provides the autonomic functions; including respiration, cardiac function, and reflexes
- Part of the Brain Steam
What is the function of the Pons within the Hindbrain?
- Relays the signals from the forebrain to the cerebellum [Connecting the forebrain to the hindbrain]
- Part of the Brain Steam
What is the function of the Cerebellum within the Hindbrain?
- Helps produce the smooth motor movements
- undergoes the neruodegeneration in spinocerebellar ataxias - jerky movements
What is the function of the Substantia Nirga within the Midbrain?
- Pars Compacta: provides input to the Basal Ganglia which supplies dopamine to the straitum
- Motor control
- Undergoes neurodeneration in Parkinsons
What is the function of the Cortex [Cerebrum] in the Forebrain?
- processing and interpreting information
What is the function of Basal Ganglia in the Forebrain?
- Voluntary motor control with some cognitive functions
What is the functions of the limbic system within the Forebrain?
- Amygdala: emotions
- Hippocampus: memory
What is the function of the diencephalon within the Function of the Forebrain?
- Thalamus: passes signals between the basal ganglia to cortex [Non-autonomic]
- Hypothalamus: hormonal control [autonomic]
What makes the Cortex so important within our brain?
- Involved in decision making [cortico-thalamic loop] -> Information to Thalamus to cortex back to Thalamus
- damage = problems with movement, speech, personality
What is the disease of the frontal cortex?
- Schizophrenia
What are the glial cells?
- Astrocytes, Oligodendrocytes, Mircoglia
What do astrocytes do?
- provide growth factors
- decrease glutamate
- support BBB
