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.

Aug. 28, 2026 Frequent micro-awakenings during sleep were linked to higher genetic risk for Alzheimer’s in healthy middle-aged adults who had no symptoms. The discovery raises the possibility that subtle changes during sleep could offer an early warning signal ...
Aug. 27, 2026 Scientists created smart nanoparticles that can both illuminate hidden glioblastoma cells during surgery and destroy microscopic cancer left behind afterward. In mice, the treatment prevented recurrence and led to 100% survival at 60 days, though it ...
Aug. 27, 2026 Researchers discovered a brain-based “brake” that can shut down chronic nerve pain in mice by calming an overactive pain circuit. Targeting this system more precisely could one day lead to powerful pain relief without affecting opioid receptors ...
Aug. 26, 2026 Early-life stress may physically alter how DNA is packaged in the brain, leaving stress-related genes primed to activate more easily years later. In mice, researchers were able to block this effect, preventing the heightened anxiety and stress ...
Aug. 25, 2026 Older adults who received the Shingrix shingles vaccine were 24% less likely to be diagnosed with dementia over four years in a study of more than 500,000 people. Researchers estimate the difference could amount to roughly one dementia case ...
Aug. 25, 2026 A major study found that adults with depression show disrupted production of new neurons in the hippocampus, potentially weakening the brain’s ability to separate new experiences from painful memories. The researchers also identified broad ...
Aug. 24, 2026 Both too little and too much sleep may be linked to faster aging throughout the body. Researchers analyzing 23 biological aging clocks found the lowest aging levels among people sleeping about 6.4 to 7.8 hours per day. Short or long sleep was also ...
Aug. 23, 2026 Researchers have uncovered a possible reason why the Alzheimer’s risk gene APOE4 can disrupt the brain long before memory problems begin. In mice, APOE4 increased a protein called Nell2, shrinking ...
Aug. 23, 2026 Older adults with mild cognitive impairment and sleep problems who took at least 5,000 IU of vitamin D daily scored more than 13% higher on a cognitive test than those taking none. The preliminary findings suggest vitamin D could be worth studying ...
Aug. 22, 2026 Mice that developed compulsive drinking after alcohol abstinence showed more than double the activity in a brain region associated with stress and addiction. Because the signal appeared before they drank again, researchers think it could eventually ...
Aug. 22, 2026 People who speak several languages may have brains that age more slowly, with four-language speakers showing brains that appeared about 13 years younger than those of monolinguals. Starting earlier and becoming highly fluent were also linked to a ...
Aug. 20, 2026 Ozempic may work in the brain in almost the opposite way scientists expected, activating hunger-linked neurons that appear essential for sustaining fat loss. The surprising discovery in mice could reveal new targets for developing even more ...
