Document Summary
Netrin: after midline, robo 3. 2 allows all receptors to be repelled by slit- Inserting light sensitive channels into neuron that open k and cl channels makes it possible to hyperpolarize neurons by presenting light (optogenetics: silencing the new neurons doesn"t affect acquisition, blocks memory retrieval. Interaural time delay (itd) (f<1. 4 khz: mso measures time difference between two ears to determine location, delay lines in mso detect coincidence of inputs from both ears, ee neurons. Vestibular system and vestibulo-ocular reflex: semicircular canals, three canals respond to angular acceleration, superior, posterior, horizontal, perpendicular to one another, canals on opposite sides of head form opposing pairs, inside each bony canal is endolymph fluids - ampulla. Inferior rectus: adduction and abduction rotate left and right, medial rectus, lateral rectus, extorsion and intorsion rotate towards nose or away. In response to small, moving targets: peak velocity is 80 degrees/second, vision is maintained during movement.
