The origin of the axon differs between primates and non-primates in the architecture of neurons, a new study reports.
Experimental observations conclude learning is mainly performed by neural dendrite trees as opposed to modifying solely through the strength of the synapses, as previously believed.
Different types of dendrites process incoming information in different ways before sending it to the body of the neuron.
One dose of psilocybin, the psychoactive compound found in magic mushrooms, increases dendritic spine density within 24 hours. The neurobiological changes lasted for a month following psilocybin exposure. Additionally, mice subjected to stress showed behavioral improvements and increased neurotransmitter activity after psilocybin exposure.
Using a snap-freezing method, researchers have been able to reveal the true structure of the connections that join neurons together in the adult brain.
A clusterization approach allows researchers to analyze dendritic spines in new ways.
Researchers have made an important discovery about the mechanisms behind learning and memory. Depending on the number of synapses, and their proximity, information is processed and stored differently.
Neurons created as a result of adult neurogenesis mature for longer and grow larger than those created during infancy. Findings suggest adult-born neurons may have a more powerful function than those created during infancy and may play a critical role in neuroplasticity.
