Reading 1: One Brain Or Two? — Gazzaniga's split-brain research illustrating the separate functions of the brain's hemispheres. Reading 2: More Experience = Bigger Brain — Mark Rosenzweig research on rats raised in highly stimulating environments compared to rats raised in plain or dull circumstances and the effects on the brain. [10]
The earliest attempts at estimating brain volume were done using measures of external head parameters, such as head circumference as a proxy for brain size. [1] More recent methodologies employed to study this relationship include post-mortem measures of brain weight and volume. These have their own limitations and strengths. [9]
The evolutionary history of the human brain shows primarily a gradually bigger brain relative to body size during the evolutionary path from early primates to hominins and finally to Homo sapiens. This trend that has led to the present day human brain size indicates that there has been a 2-3 factor increase in size over the past 3 million years ...
Here's the surprising reason why human brain size has shrunk by 10 percent. Thanks so much, evolution. ... 800-290-4726 more ways to reach us. Sign in. Mail. 24/7 Help. For premium support please ...
A larger brain results in larger capacity for adaptive knowledge; More adaptive knowledge increases fitness of organisms; Using evolutionary simulation, the researchers were able to confirm the existence of hypothesised relationships. Results concerning the cultural intelligence hypothesis model showed that larger brains can store more ...
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
The expensive tissue hypothesis (ETH) relates brain and gut size in evolution (specifically in human evolution).It suggests that in order for an organism to evolve a large brain without a significant increase in basal metabolic rate (as seen in humans), the organism must use less energy on other expensive tissues; the paper introducing the ETH suggests that in humans, this was achieved by ...
