Document Summary
Experimental neuropsychology (cognitive neuropsychology): (cognitive neuroscience) : focus is on how human behavior from brain activity. Fritsch and hitzig: said the frontal cortex of a dog was important for normal movement: the first higher cognitive function that was successfully localized was language. Loss of comprehension of language associated with the preservation of speech. Anatomical studies: cellular constituents of the brain: Electrical properties of the neuron: neurons conduct electricity impulses throughout the entire length, galvani discovered: muscles and nerve cells produce electricity. Fritsch and hitzig: observed that discrete electrical stimulations of parts of the cortex of a dog could result in movements: sherrington: control of reflex movements in mammals:he created the word: Neurotransmitters: neurons communicate with each other by releasing chemicals. Loewi: vagus nerve (the nerve that weakens the heart) , he showed that the vagus must release substances that produces the change in heart beat.
