Studies of brain function in normal human brains support this same conclusion, showing activity in the brain’s visual areas while subjects imagined visual objects and scenes. [ 62 ] The previously mentioned and numerous related studies have led to a relative consensus within cognitive science , psychology, neuroscience, and philosophy on the ...
Imagination involves many different brain functions, including emotions, memory, and thoughts. [ 69 ] [ 70 ] Visual imagery involves a network of brain areas from the frontal cortex to sensory areas, overlapping with the default mode network , and can function much like a weak version of afferent perception.
Other patients represent the opposite, where memory for colors and shapes is unaffected but spatial memory for previously known places is greatly impaired. [30] These case studies show that these two types of visual memory are located in different parts of the brain and are somewhat unrelated in terms of functioning in daily life.
The brain activity is tied to one thing, like a specific object or task. The goal is to figure out how the brain represents specific things (like seeing a face or recognizing a word) when you're actively engaging with something. For example, with fMRI scans, researchers can track brain activity while people look at different objects or images.
Cognitive development is a field of study in neuroscience and psychology focusing on a child's development in terms of information processing, conceptual resources, perceptual skill, language learning, and other aspects of the developed adult brain and cognitive psychology.
The sensory nervous system is a part of the nervous system responsible for processing sensory information. A sensory system consists of sensory neurons (including the sensory receptor cells), neural pathways , and parts of the brain involved in sensory perception and interoception .
When placed at different arms of the cross maze however, the rat still went in the correct direction to obtain the food because of the initial cognitive map it had created of the maze. Rather than just deciding to turn right at the intersection no matter what, the rat was able to determine the correct way to the food no matter where in the maze ...
Although the human brain represents only 2% of the body weight, it receives 15% of the cardiac output, 20% of total body oxygen consumption, and 25% of total body glucose utilization. [138] The brain mostly uses glucose for energy, and deprivation of glucose, as can happen in hypoglycemia, can result in loss of consciousness. [139]
