Thought
Thought or thinking is a mental process which allows beings to model the world, and so to deal with it effectively according to their goals, plans, ends and desires.
Thinking involves manipulation of information, as when we form concepts, engage in problem solving, reason and make decisions. Thinking is a higher cognitive function and the analysis of thinking processes is part of cognitive psychology.
The basic mechanics of the human brain reflect a process of pattern matching or rather recognition. In a "moment of reflection", new situations and new experiences are judged against recalled ones and judgments are made. In order to make these judgments, the intellect maintains present experience and sorts relevant past experience. It does this while keeping present and past experience distinct and separate. The intellect can mix, match, merge, sift, and sort concepts, perceptions, and experience. This process is called reasoning. Logic is the science of reasoning.

Nov. 25, 2025 Scientists have found that a mutation tied to Alzheimer’s disrupts the production and quality of exosomes—tiny cell-made communication packets. Cells with the defective SORLA protein generate fewer exosomes and ones far less able to support ...
Nov. 24, 2025 Hypertension begins harming the brain surprisingly early, even before measurable blood pressure increases. Key cells related to blood vessels, signaling, and myelin maintenance begin aging prematurely and malfunctioning. These disruptions resemble ...
Nov. 23, 2025 Researchers have uncovered a surprising way the brain switches pain on, revealing that neurons can release an enzyme outside the cell that activates pain signals without disrupting normal movement or sensation. This enzyme, called VLK, modifies ...
Nov. 23, 2025 Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, activating these cells improved cognitive ...
Nov. 22, 2025 Scientists discovered that lowering a specific molecule helps microglia switch into a protective state that quiets brain inflammation in Alzheimer’s. A small group of these cells seems to have an outsized ability to keep the brain healthier. When ...
Nov. 22, 2025 A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach the brain without invasive surgery. When paired ...
Nov. 21, 2025 Researchers uncovered how estrogen subtly reshapes learning by strengthening dopamine reward signals in the brain. Rats learned faster when estrogen levels were high and struggled when the hormone’s activity was blocked. The findings help explain ...
