Feb 21st 2025, 12:58

Researchers used visual threat manipulation in the virtual reality environment and thermal stimulation to investigate how the brain perceives pain. They found that the brain perceives pain more strongly when the perceived pain is out of alignment with reality. In particular, pain was amplified when unexpected events occurred.

Feb 21st 2025, 12:58

Researchers have applied a visualization technique to depict the brain's activity related to visual perception as geometric patterns. They visualized different shapes as the ever-changing neuronal activity in the temporal and frontal lobes of the brain during object recognition and recalling memories. This achievement promises further extraction of brain activity observed in various aspects of daily life.

Feb 21st 2025, 12:55

Researchers have discovered a fundamental mechanism that affects the size of the pupil, namely our breathing. The study shows that the pupil is smallest during inhalation and largest during exhalation -- something that could affect our vision.

Feb 20th 2025, 16:43

Human evolution has revolved around food, from identifying and foraging for it to growing and preparing it. Researchers have identified a region in the brain's visual cortex that responds to food and have developed a theoretical framework that could explain the origins of this selectivity. The team outlines how visual and nonvisual signals contribute to the brain's cortical responses when people were shown images of food. Researchers also found that images of food in context elicited additional responses in the brain, as compared to images without context. One explanation for this finding is that seeing these objects in their natural context might invoke the varied experiences of interacting with food or other information related to identifying food as just that: food. For example, signals that could influence food selectivity in the visual cortex include color, social cues or the motor actions of eating.
