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.
This three-layer cortex is still conserved in some parts of the human brain such as the hippocampus and is believed to have evolved in mammals to the neocortex during the transition between the Triassic and Jurassic periods. [69] [68] After looking at history, the mammals had little neocortex compared to the primates as they had more cortex. [70]
The neurons associated with remembering the location and object are often found in the primate hippocampus. These spatial view cells do not only recall specific locations, but they also remember distances between other landmarks around the place in order to gain a better understanding of where the places are spatially.
The hippocampus is anatomically connected to parts of the brain that are involved with emotional behavior, including the septal area, the hypothalamic mammillary bodies, and the anterior nuclear complex in the thalamus. MacLean proposed that the associated structures of the limbic lobe be included in what he termed as the limbic system. [14]
Her theory about human behavior, and the problems we create with that behavior, distinguishes the prefrontal cortex as uniquely different from the rest of the neocortex. The prefrontal cortex, with its agenda of integration, is the part of the brain that can get the other parts to work together for the good of the individual.
Typically, the hippocampal formation is said to included the dentate gyrus, the hippocampus, and the subiculum. [2] The presubiculum, parasubiculum, and the entorhinal cortex may also be included. [3] The hippocampal formation is thought to play a role in memory, spatial navigation and control of attention.
The dentate gyrus (DG) is one of the subfields of the hippocampus, in the hippocampal formation.The hippocampal formation is located in the temporal lobe of the brain, and includes the hippocampus (including CA1 to CA4) subfields, and other subfields including the dentate gyrus, subiculum, and presubiculum.
Furthermore, in all animals, the nervous system is the organ of behavior. Therefore, every biological and behavioral variable that influences behavior must go through the nervous system to do so. Present-day research in behavioral neuroscience studies all biological variables which act through the nervous system and relate to behavior. [10]
