Tinnitus: Disturbed by phantom sounds

Ever heard a ringing sound that isn’t really there? That’s tinnitus - your brain making noise without an external source. This brain misfire can turn a minor annoyance into a life-altering condition. Once thought to be just an ear problem, research reveals it’s deeply rooted in the

Sex differences in how we move our eyes ... wink, wink

I knew that men and women look at different things and suspected they sometimes look differently at things. But it was a surprise to learn that men and women move their eyeballs differently as well, in a fundamental neurological way. Eye movement tracking may be a niche, but that'

Exploding Head Syndrome - a banger blogpost

Imagine you are about to doze off to sleep when a loud bang echoes inside your head. It sounds like an explosion, a sudden clap of thunder, or a firework going off, but no one else can hear it. Exploding Head Syndrome is a puzzling and rare sleep disturbance. People

Why do some new words stick in our memory while others don't?

Why do some new words stick in our memory while others don't?

Have you ever come across a word for the first time and remembered it instantly, while others seem to slip away the moment you read them? By studying how the brain processes unfamiliar words, called pseudowords, researchers have now uncovered key insights into how we store and recall language. Among

The power of light: How blue light impacts mood and self-perception

Light has an undeniable influence on how we feel, and this connection goes beyond just how bright or dim our environment is. In recent years, scientists have discovered that different sorts of light play a significant role in influencing our moods and emotions. Studies have shown that exposure to natural

Forgetting part II: Error in our brain's ability to forget stuff impact mental health

The human brain is an astonishing machine, storing and managing a vast number of memories every day. This process is driven by a complex network of billions of brain cells, which work together to preserve, and retrieve information. When we learn something new, specific neurons undergo physiological changes, creating a

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
