We are born with a smooth brain (like rats and rabbits) and the ridges form as we age. * ap on top of the brain from video. Contains the cell bodies, dendrites and axon terminals of neurons, so it is where all synapses are. Is made of axons connecting different parts of grey matter to each other. White matter is fat, connects the different parts of the brain. Brain stimulation (you can stick and electron to a neuron to see if it res) Don"t want to react like getting chased like a tiger if thats your dream. Last part of the brain to fully develop.
