A heuristic model of the neural pathway of the Papez circuit shows the connections between its different parts. Based on Papez's experiment with aggression in rats and other studies, it was initially believed that the circuit was involved with emotion. The circuit connects the hypothalamus and the cortex and acts as the emotional system of the ...
James Wenceslas Papez (/ peɪpz /; [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. Specifically, Papez hypothesized that the hippocampus, the cingulate gyrus (Broca's callosal lobe), the ...
The limbic system, also known as the paleomammalian cortex, is a set of brain structures located on both sides of the thalamus, immediately beneath the medial temporal lobe of the cerebrum primarily in the forebrain. [1] Its various components support a variety of functions including emotion, behavior, long-term memory, and olfaction.
The role of the limbic system in emotion was first explained by James Papez in 1937 within his paper titled "A proposed mechanism of emotion". The model described is known as the Papez circuit. The Papez circuit highlighted the presence of neuronal pathways between the vestibular and the limbic system. [28]
Philip Bard (1898–1977) was a doctoral student of Cannon's, and together they developed a model of emotion called the Cannon–Bard Theory. [2][3] Cannon was an experimenter who relied on studies of animal physiology. Through these studies, Cannon and Bard highlighted the role of the brain in generating physiological responses and feelings; a ...
The triune brain is a model of the evolution of the vertebrate forebrain and behavior, proposed by the American physician and neuroscientist Paul D. MacLean in the 1960s. The triune brain consists of the reptilian complex (basal ganglia), the paleomammalian complex (limbic system), and the neomammalian complex (neocortex), viewed each as ...
Another is the Papez circuit linking the hypothalamus to the limbic lobe. There are several neural circuits in the cortico-basal ganglia-thalamo-cortical loop. These circuits carry information between the cortex, basal ganglia, thalamus, and back to the cortex.
Early stages of research on emotions and the brain was conducted by Paul Broca, [4] James Papez, [5] and Paul D. MacLean. [6] Their work suggests that emotion is related to a group of structures in the center of the brain called the limbic system. The limbic system is made up of the following brain structures:
