Psychedelic Spurs Growth of Neural Connections Lost In Depression

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.

Watching the Brain Learn

In older mice, adult neurons in the primary visual cortex with an increased number of "silent synapses" and lacking PSD-95, showed the same structural changes only seen previously in younger animals.

Adult-born neurons grow more than their infancy-born counterparts

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.

How gene mutation causes autism and intellectual disability

Genetic mutations in Usp9X results in the brain growing fewer synapses during development. The mutation also causes hyperactivity and an increased risk of anxiety. The findings shed new light on the cause of autism and other intellectual disabilities.

Fundamental insight into how memory changes with age

New memories are laid down via different mechanisms in older mice compared to younger mice. Additionally, synaptic changes linked to new memory formation were harder to modify in older mice.

Lack of oxygen doesn’t kill infant brain cells, as previously thought

A lack of oxygen as a result of preterm birth does not cause hippocampal neurons to die but does impair hippocampal development. Hypoxia causes hippocampal cells to fail to mature normally, causing a reduction in long-term potentiation and impaired learning.
