What is actin?
Cytoskeletal element responsible for movement of filopodia
What is Netrin?
Chemoattractant that draws axonal growth cones toward the midline
What is Robo?
Receptor that when activated prevents DCC receptor activation
What is Semaphorin?
Chemoreceptor that causes the axonal growth cone to move away from midline
What is PAR protein?
Selectively expressed in neutrites that will become axons
What is neurexin?
Protein responsible for clustering of synaptic vesicles
What is neuroligin?
Protein responsible for clustering of receptors
What is a microtubule?
Cytoskeletal element that spans the entire elongating axon
What is neurotrophin?
Molecule required to maintain a synapse after it has already been formed
What is CAM?
involved in axon fasciculation
T/F: Hebb’s postulate states that synapses in which both neurons have synchronized activity will be retained
True
T/F: After birth, the brain primarily matures by creating new neurons
False
T/F: A critical period refers to the time Fram during which an organism is able to develop a specific behavior
True
T/F: The critical period for peer social skills occur prior to the critical period for visual development
False
T/F: Critical periods for different behaviors typically occur at the same time & have similar lengths
False
T/F: Keeping eyes continuously shut early in life prevents the formation of ocular dominance columns
True
T/F: During esotropia, inputs from both eyes to visual cortex remain active
False
T/F: As it relates to critical periods, sign language exhibits similar patterns as spoken language
True
T/F: Calcium entry through ion channels is important for establishing behaviors associated with critical periods
True
T/F: There is no evidence that hearing exhibits a critical period
false
T/F: Following a brain injury, neurogenesis in the sub ventricular zone returns to levels observed in utero
False
T/F: After an injury, Schwann cells prevent axon growth in the peripheral nervous system
False
T/F: NMDA receptor activation contributes to neuron death during traumatic brain injury
True
T/F: Many of the same molecules involved in synapse formation are involved in nervous tissue repair
True
T/F: Following a stroke, damage to any brain region will typically regerate
False
T/F: A patient exhibits motor dysfunction following a stroke. It is possible for this patient to gradually regain some of this motor function
true
T/F: If an axon in the peripheral nervous system is damaged, it can repair itself
True
T/F: The olfactory bulb does not regenerate following damage
False
T/F: In the peripheral neurons, trophic factors from target cells immediately stop being released
False
T/F: Following an injury in the central nervous system, glia release chemorepellant molecules
True
