Encyclopedia
James Papez was an American
neuroanatomist. Papez received his MD
from the University of Minnesota
College of Medicine
and Surgery
. He is most famous for his 1937 description of the Papez circuit
which is a neural
pathway in the brain
thought to be involved in the cortical
control of emotion
. He was a neurologist at Cornell University when he published a journal article in which he outlined a "new" circuit to account for emotion. He hypothesized that the hippocampus, the cingulate gyrus (Broca's callosal lobe), the hypothalamus, the anterior thalamic nuclei, and the interconnections among these structures constituted a harmonious mechanism which elaborate the functions of emotions. Papez never mentioned Broca's limbic lobe
but others noted that his circuit was very similar to Broca's great limbic lobe.

Described by James Papez in 1937, the Papez circuit of the brain is one of the major pathways of the limbic system and is chiefly involved in the cortical control of emotion. The Papez circuit plays a role in storing memory....

Neuron
A neuron is an electrically excitable cell that processes and transmits information by electrical and chemical signaling. Chemical signaling occurs via synapses, specialized connections with other cells. Neurons connect to each other to form networks. Neurons are the core components of the nervous...

Brain
The brain is the center of the nervous system in all vertebrate and most invertebrate animals—only a few primitive invertebrates such as sponges, jellyfish, sea squirts and starfishes do not have one. It is located in the head, usually close to primary sensory apparatus such as vision, hearing,...

Emotion
Emotion is a complex psychophysiological experience of an individual's state of mind as interacting with biochemical and environmental influences. In humans, emotion fundamentally involves "physiological arousal, expressive behaviors, and conscious experience." Emotion is associated with mood,...
