Forgetting part I: Remember to forget - how our brain deletes memories

Forgetting part I: Remember to forget - how our brain deletes memories

The human brain is a system designed to store and recall huge amounts of information throughout a lifetime. At the heart of this process are our brain cells, called neurons, the brain’s fundamental units. When we acquire new information, specialized memory neurons that store the specific memory change. They

Robots achieve consciousness through simulations of evolution

Robots achieve consciousness through simulations of evolution

Can machines attain consciousness — perceiving, feeling, and being conscious of their surroundings? A path toward machine intelligence could be using Darwinian evolution to create artificial brains for mobile, potentially sentient robots. Creating artificial evolution In recent studies, scientists have explored using evolution within computer models to understand intelligence and cognition.

Sucker for neuroscience. Eight arms, one brain: How do they manage?

Sucker for neuroscience. Eight arms, one brain: How do they manage?

The octopus is a master of movement and control. Each of its eight arms is a soft, flexible structure without bones, allowing movement in nearly limitless ways. Adding to this complexity, the arms are covered in hundreds of highly sensitive suckers, each capable of moving independently. Despite this sophisticated system,

Dogs' sleep waves correlate to their intelligence - the dog g-factor

Dogs' sleep waves correlate to their intelligence - the dog g-factor

Sleep spindles are the name for distinct brain wave patterns observed during sleep. These waves, lasting up to six seconds, are common in non-rapid eye movement (non-REM) sleep and are generated by a specific circuit in the brain (the thalamocortical circuit). While studies on sleep-dependent learning assume a direct, causal

Do amphetamines boost brainpower when used in obesity treatment?

Do amphetamines boost brainpower when used in obesity treatment?

Amphetamines are a category of drugs that are known for their ability to increase dopamine levels in the brain, particularly in areas related to reward and executive function. Executive function is the brain's ability to plan, make decisions, and control impulses to reach goals. This increased dopamine activity

Can neurostimulation boost endurance? Sry, there is still no easy way to get into shape

Can neurostimulation boost endurance? Sry, there is still no easy way to get into shape

Exploring the limits of human endurance has inspired innovative research into brain stimulation techniques. Transcranial direct current stimulation, or tDCS, is a non-invasive method where low-intensity electrical currents are applied to the scalp to influence brain activity. It has shown promise in enhancing exercise performance in strength and cycling studies,

The development of our spine: Growing a tail, then losing it again

The development of our spine: Growing a tail, then losing it again

In the earliest weeks of human development, we grow a tail. The tail’s growth and disappearance is a glimpse into the delicate balance of growth and regression during our creation in the womb. This process, called neurulation, forms the spinal cord and surrounding tissues. Researchers found that the process
