Drugs targeting amyloid plaques have failed to show efficacy in clinical trials. A new approach is needed to tackle AD ...

Markita Landry is the first to admit that the two applications her research addresses – imaging brain chemistry and delivering genetic material into plants – are rather divergent.

Labeled diagram with its action and pathways. Scheme with closeup presynaptic axon, terminal, synaptic cleft, dendrite and receiving cells. Anatomy neyron and synapse. Signaling in the brain. Cells ...

It can detect single aggregates of Aβ and tau inside and outside synapses. Tau aggregates appear inside synapses from human brain samples with Aβ pathology. The method can be adapted to study other ...

A new study investigated the brain circuits involved in psychosis—a condition characterized by delusions, hallucinations, ...

the addictive potential of some drugs of abuse and the elimination of synapses in neurodegenerative diseases. The two major forms of long-lasting synaptic plasticity in the mammalian brain ...

The interlinking of neurons during childhood results in many more synapses than remain in the adult brain. The reduction in synapses that happens as a person grows up is thought to be adaptive ...

When stimulated, nerve cells generate new tendrils of connection to other nerve cells, called synapses. All learning hinges on the brain’s capacity to form new nerve cell connections ...

A man with paralysis who had electrodes implanted in his brain can pilot a virtual drone through an obstacle course simply by imagining moving his fingers. His brain signals are interpreted by an ...

Cognitively normal human brain samples collected at autopsy in early 2024 contained more tiny shards of plastic than samples collected eight years prior, according to a new study. Overall ...
