Document Summary

Cell body with axons that all have tons of dendrites. There are synapses on the axon as well. In the nmj, you can see the synapses. In the cns, you little dots are synapses (100s of them) can"t. between 100 and 500 trillion synapses (connections). inputs all the time. The brain has over a 100 billion neurons which make. The brain is getting all this input all the time, but is getting rid of all the info that is not meaningful. Hormones, like estradiol and testosterone can increase the number of synapses and change your cognition. If you deprive a horny rat of food, they will not go looking for food but continue to look for sex b/c their brain has been filtered to think sex is more important. If you"re changing synapses, you"re changing a protein. So the protein"s molecular machinery is changing as well.
