Alzheimer's disease disrupts some forms of visual memory by degrading a newly identified brain circuit that connects the primary visual cortex of each hemisphere.
Electrical stimulation improves verbal memory for those with responsive neurostimulation implants when activated during certain memory tasks.
In natural vision, visual memories of an image are affected by the size of the vision on the retina.
Video games high in action content help players to become quicker learners, researchers report.
While commonly implicated in long-term memory, researchers report the hippocampus plays a critical role in short-term memory and decision making.
Aphantasia is marked by the inability to generate visual images in the mind's eye. Researchers explore the neurobiological basis for the disorder.
As novel visual patterns become familiar, stark changes occur in the visual cortex. Gamma rhythms give way to low-wave beta waves, and the neural activity switches from PV neurons in favor of inhibitory SOM neurons.
New research indicates the existence of an unconscious iconic memory store that supports predictions made by the global workspace theory of consciousness. It also shows that visual masking does not erase memory traces of masked stimuli but only limits
conscious access.
People with prediabetes who have higher than average blood sugar levels are at increased risk of cognitive problems and vascular dementia.
Findings contradict the assumption the visual system categorizes objects based on simple features alone.
In visual working memory, the brain immediately transfers the memory of object shifts by re-encoding the memory among neurons in the opposite brain hemisphere.
While people with aphantasia lack visual imagery ability, they have intact spatial memory. Findings suggest mental imagery recall and spatial memory may be stored differently in the brain.
