Now, a new study in rodents describes how learning still occurs in the absence of an immediate incentive. Wed, 09 Aug 2023 13:06:14 EDT https: //www.koonmotors.com/releases/2023/08/230809130614.htm https: //www.koonmotors.com/releases/2023/08/230807152147.htm One of the most actively debated questions about human and non-human culture is this: under what circumstances might we expect culture, in particular the ability to learn from one another, to be favored by natural selection? Researchers have developed a simulation model of the evolution of social learning. They showed that the interplay between learning, memory and forgetting broadens the conditions under which we expect to see social learning to evolve. Mon, 07 Aug 2023 15:21:47 EDT https: //www.koonmotors.com/releases/2023/08/230807152147.htm https: //www.koonmotors.com/releases/2023/08/230803213817.htm Research has identified a mechanism through which insulin-like growth factors facilitate brain plasticity. The insulin super-family of hormones, including insulin, insulin-like growth factor 1 (IGF1), and insulin-like growth factor 2 (IGF2), play a crucial role not only in regulating blood sugar, metabolism, and growth, but also in healthy brain development and function, including learning and memory. These hormones can enter the brain through the bloodstream from the liver or can be synthesized directly in neurons and glial cells within the brain. They bind to receptors, including the IGF1-Receptor, activating signals that modulate neuron growth and activity. Disruption of this signaling pathway is involved in cognitive decline and diseases such as Alzheimer's.

The team demonstrated that high-frequency brain waves in the amygdala, a hub for emotional processes, and the hippocampus, a hub for memory processes, are critical to enhancing memory for emotional stimuli. Disruptions to this neural mechanism, brought on either by electrical brain stimulation or depression, impair memory specifically for emotional stimuli.

The latter, for example, insulate the 'wiring' of nerve cells or guarantee optimal working conditions for them. A new study has now discovered another function in rodents: The results suggest that a certain type of glial cell plays an important role in spatial learning.

However, research has shown that sleep deprivation is bad for your memory. Now, neuroscientists have discovered that what you learn while being sleep deprived is not necessarily lost, it is just difficult to recall. Together with his team, he has found a way to make this 'hidden knowledge' accessible again.
