“The alcohol increased the number of glutamate receptors at the synapse and this increased the fear response. These findings could have relevance for PTSD if the same holds true for humans. It also suggests that people that binge drink or use alcohol to self-medicate may actually be doing more harm.”

“Transcranial magnetic stimulation in the dorsolateral prefrontal cortex region of the brain has been shown to reduce cravings in cocaine, heroin, alcohol, and now methamphetamine users. Although the mechanism is still unclear, this non-invasive technique continues to show promise as a treatment for substance abuse.”

“This 2022 review summarizes the evidence demonstrating that exercise training is a highly effective, economical, non-pharmacological strategy to maintain and improve cognitive function in aging. It also describes some of the mechanisms that drive the beneficial effects of exercise on cognitive function, including improved blood circulation, synaptic plasticity, and neurogenesis, among others.”

“Lipid rafts – cholesterol-filled "bubbles" found in neuronal cell membranes – play a crucial role in synaptic plasticity and memory formation. However, lipid rafts undergo extensive changes during aging, ultimately contributing to cognitive decline.”

“Then they subjected the young mice to a battery of spatial learning and memory tests involving mazes and escape tunnels. They found that the young mice that received fecal microbial transplants from the aged mice showed marked deficits in spatial learning and memory capacity.”

“Resistance exercise adaptations, muscle memory, and aging The only way to improve muscle strength and size is to perform resistance exercises. Not everyone will respond the same way to resistance training due to many individual factors, including training history, age, and sex.”

“The loss of synapses promotes the collapse of neural networks important for memory and cognition and drive the dementia associated with Alzheimer's disease. Key players in synaptic integrity are synaptic proteins, which play critical roles in neurotransmission and neuronal development.”
