Exam 1 Flashcards
Basal ganglia
Movement control
Lambic system
Responsible for emotional memory, regulation
Midbrain (reticular formation)
Sleeping and arousal, temperature and motor control
Pons
Motor and sensory nuclei to face (not really important for class)
Medulla
Makes the heart beat
Transition of brain to spinal cord, heart rate, breathing
Cerebellum
Motor coordination and learning
Rett’s syndrome
Esme:
- she doesn’t use her hands or speak
- brain shrinks
Fragile X syndrome
Lack of neuronal cell death
- doesn’t kill off unused synapses
- head size bigger than normal
- keep all neuronal connections
- results in mental retardation
Disorder in neuronal migration result in what?
Brain malformation
Ex) Pachygyria
Chemoattractant
Chemicals that attract growth come of neuron
Chemorepellant
Chemicals that repel growth cones of neurons
Amblyopia (lazy eye)
Muscles in the eye are impaired
The information received to each eye is different so the brain is working independently in each eye.
Can fix this early on but if you wait too long the brain function will never return
You lose the neurons firing to this eye and eventually can’t make anymore
Echolalia
Communicative feature of autism
- repeat the last word of everything a person says
- the words are supposed to be processed but it’s not
Agonist
Initiates normal effects of the receptor
Antagonist
Prevents receptor from being activated by other ligands
2 types
- competitive : something else binds besides the correct hormone (direct)
-non competitive : something binds next door which changes the composition of the correct target then the hormone is unable to bind (indirect)
