Karl H. Pribram (/ ˈ p r aɪ b r æ m /; German: [ˈpʁiːbram]; February 25, 1919 – January 19, 2015) was a visionary neurosurgeon, neuroscientist and theoretical philosopher described by his peers as the “Einstein of Brain Science” [1] and the “Magellan of the Mind” for his groundbreaking research into the function and roles of the limbic system, frontal lobes, and temporal lobes ...
These landmarks are processed by the hippocampus together to provide a graph of the environment through relative locations. [17] Alex Siegel and Sheldon White (1975) proposed a model of acquisition of spatial knowledge based on different levels. The first stage of the process is said to be limited to the landmarks available in a new environment.
The hippocampus (pl.: hippocampi; via Latin from Greek ἱππόκαμπος, 'seahorse'), also hippocampus proper, is a major component of the brain of humans and many other vertebrates. In the human brain the hippocampus, the dentate gyrus , and the subiculum are components of the hippocampal formation located in the limbic system .
Place cells were first discovered by John O'Keefe and Jonathan Dostrovsky in 1971 in rats' hippocampuses. [ 6 ] [ 7 ] They noticed that rats with impairments in their hippocampus performed poorly in spatial tasks, and thus hypothesised that this area must hold some kind of spatial representation of the environment.
Frank Dance's helical model of communication was initially published in his 1967 book Human Communication Theory. [161] [162] [163] It is intended as a response to and an improvement over linear and circular models by stressing the dynamic nature of communication and how it changes the participants. Dance sees the fault of linear models as ...
The Great Hippocampus Question was a 19th-century scientific controversy about the anatomy of ape and human uniqueness. The dispute between Thomas Henry Huxley and Richard Owen became central to the scientific debate on human evolution that followed Charles Darwin 's publication of On the Origin of Species .
While the dorsal hippocampus is involved in spatial memory formation, the left hippocampus is a participant in the recall of these spatial memories. Eichenbaum [ 19 ] and his team found, when studying the hippocampal lesions in rats, that the left hippocampus is "critical for effectively combining the 'what', 'when', and 'where' qualities of ...
LTP in the hippocampus is an important model for neural plasticity that contributes to learning and memory. [7] Schaffer collaterals are the axons of the neurons in the CA3 regions of the hippocampus that form synapses in the CA1 regions. The hippocampus is a part of the feedback process that sends signals to stop cortisol production.
