Jumping spiders can distinguish between living and non-living objects based upon their movement, a new study reports.
While commonly implicated in long-term memory, researchers report the hippocampus plays a critical role in short-term memory and decision making.
Findings suggest prediction may be a general feature of animal nervous systems in supporting quick behavioral changes.
Infants take less than one second to completely process visual information. They also have the same temporal limitations in visual processing as adults.
Researchers propose a new theory of what happens in the brain when we experience familiar seeming visual stimuli. The theory, dubbed sensory referenced suppression, suggests the brain understands different levels of activation expected for sensory input and corrects for it, leaving behind the signal for familiarity.
Findings contradict the assumption the visual system categorizes objects based on simple features alone.
When convolutional neural networks are trained under experimental conditions, they are deceived by the brightness and color of a visual image in similar ways to the human visual system.
Researchers have identified a network of genes in Zebrafish that regulate the process of determining whether certain neurons will regenerate.
fMRI study reveals dogs do not have a specific face area similar to that of primates. Dogs' brain activity showed little response to faces but increased in response to seeing another dog over a human.
Novel technology allows researchers to understand how a fruit fly's brain processes color.
It seems that flies are as susceptible to optical illusions as humans. Turning on and off some neurons that govern motion detection in flies, researchers were able to alter the insects' perception of illusory motion.
Animals slowly shift their likelihood of detecting stimulus changes over ten minutes. Researchers found the activity of neural populations from the V4 visual area and prefrontal cortex slowly drifted together with the behavioral fluctuations. The slow drift acts as an impulsivity signal.
