James Wenceslas Papez (/ p eɪ p z /; [1] [2] [3] 1883–1958) was an American neuroanatomist, most famous for his 1937 description of the Papez circuit, a neural pathway in the brain thought to be involved in the cortical control of emotion.
In a dissected brain, the inferior medial view shows the curved shape of the structures of the Papez circuit in the brain. The Papez circuit involves various structures of the brain. It begins and ends with the hippocampus (or the hippocampal formation). Fiber dissection indicates that the average size of the circuit is 350 millimeters.
As explained in his 1996 book, The Emotional Brain, [2] LeDoux developed an interest in the topic of emotion through his doctoral work with Michael Gazzaniga on split-brain patients in the mid-1970s. [3] Because techniques for studying the human brain were limited at the time, he turned to studies of rodents where the brain could be studied in ...
It focuses more broadly on the depression circuit in the brain that links the prefrontal cortex, which is involved in memory, and the subcortical regions including the amygdala and hippocampus ...
The reward system (the mesocorticolimbic circuit) is a group of neural structures responsible for incentive salience (i.e., "wanting"; desire or craving for a reward and motivation), associative learning (primarily positive reinforcement and classical conditioning), and positively-valenced emotions, particularly ones involving pleasure as a core component (e.g., joy, euphoria and ecstasy).
A breakthrough brain circuit discovery may lead to new treatments for anxiety and stress disorders, and potentially a pill providing the benefits of yoga.. Researchers from the Salk Institute in ...
The binding problem refers to the overall encoding of our brain circuits for the combination of decisions, actions, and perception. It is considered a "problem" due to the fact that no complete model exists. The binding problem can be subdivided into the four areas of perception, neuroscience, cognitive science, and the philosophy of mind. It ...
2024 was packed with health care innovations, from a new blood test detecting Alzheimer’s disease to deep brain stimulation reversing paralysis. Heading into the New Year, medical experts are ...
