BI110 Lecture Notes - Lecture 2: Vestibular Nuclei, Semicircular Canals, Visual Acuity
Document Summary
Members of all the different species in the lineage leading to humans. Blue tits: small birds that learn to peck through aluminum caps of milk bottles learn through observation. Sea gypsies learn to swim before walking crazy swimming skills allows them to develop crazy visual acuity (example of culture shaping brain) Difficulty relating signals deficit in being able to communicate orally in real time. Diff exercises to improve her cognition function. Neurotransmitters bind to receptors on postsynaptic cell membrane creating new signal in postsynaptic neuron. Dendrites form a finely branched field that receives input from many other nerve cells/receptors: degree of branching widely varied amongst neurons, more branches more inputs from more sources. Neurons transmit their output along axons (either a single axon branch of a few) Consists of 3 semicircular canals that detect movement in the horitzontal & vertical planes and movement forwards & backwards.
