what is the main function of the limbic system - emotionally significant stimuli activate SENSORY pathways that trigger the HYPOTHALAMUS to modulate the ANS response (heart rate, blood pressure...) - accumpanying ANS changes to emotional response (amygdala → hippocampus → fornix) - information about emotionally significant stimuli also conveyed to the cortex directly (from hypothalamus) and indirectly (via cingulate) to integrate a motor response to these stimuli - memory and learning als...

What does the thalamus do? - 1. relay station (receives info and tells it where to go) 2. receives sensory fibers from optic tract, ears, and spinal cord 3. receives motor info from cerebellum 4. projects fibers to the cerebrum 5. receives messages from all the sensory receptors and relays it to the proper part of the cerebrum What does the cerebellum do? - 1. coordinates movement and balance 2. processes sensory info and receives input from muscles 3. associated with ataxia (uncoordinate...

may be defined as a shared code used for representing concepts through the use of symbols, and the rules that dictate how those symbols are combined to make meaning (Owens, Metz & Farinella, 2011). It can be spoken, written or conveyed via manual gesture. Its symbols include speech sounds, written letters, words, signs, and its grammar sets forth the rules for using and assembling the symbols for meaning. As users, we are called upon to both express language (speak it, write it, sign it) and com...
