Memory like a sieve – or not

Humans are not only capable of forming memories but also recalling these memories years later. However, with advancing age many of us face difficulties with forming new memories, a process usually referred to as age-induced ...

How the brain reacts to loss of vision

If mice lose their vision immediately after birth due to a genetic defect, this has a considerable impact, both on the organisation of the cerebral cortex and on memory ability. This is the conclusion drawn by researchers ...

Synapses of the reward system at stake in autistic disorders

Autism spectrum disorders are a heterogeneous group of neurodevelopmental disorders, one of the main characteristics of which is impaired social communication. But what happens in patients' brains that disrupts their social ...

Alzheimer's disease: How amyloid aggregates alter neuronal function

While the harmful effects of amyloid peptide aggregates observed in Alzheimer's disease are well established, the mechanism through which they act on brain cells remains ill-defined. Researchers from CNRS and universite de ...

Memory molecule limits plasticity by calibrating calcium

The brain has an incredible capacity to support a lifetime of learning and memory. Each new experience fundamentally alters the connections between cells in the brain called synapses. To accommodate synaptic alterations, ...

Receptors key to strong memories

When we create a memory, a pattern of connections forms between neurons in the brain. New work from UC Davis shows how these connections can be strengthened or weakened at a molecular level. The study is published Feb. 27 ...
