Targeting Alzheimer’s: New Unorthodox Approaches

Alzheimer’s disease affects an estimated 5 million individuals in the US and causes a devastating loss of cognitive function due to the buildup of beta-amyloid and tau proteins in the brain. Previous efforts to combat this disease have focused on developing drugs that target beta-amyloid, but such treatments have been unsuccessful in patients so far. […]

New Developments in Treating Parkinson’s Disease

Parkinson’s disease (PD) is the second most common neurodegenerative disease that affects more than 10 million people worldwide. The disease primarily results from selective degeneration of dopaminergic neurons in the substantia nigra pars compacta part of the brain. Its key clinical features include motor symptoms of rigidity, tremor, and bradykinesia. However, recent findings have confirmed that the […]

Connection Between Brain, Depression and Effectiveness of Chemotherapy

Chemotherapy is a type of therapy that uses various, rather aggressive, medicines to eliminate cancer cells from the body or slow down the growth of tumors. Cancer cells are different from normal cells as they reproduce a lot faster. Chemotherapy specifically targets the fast dividing cells and thus affects cancer cells the most. However, chemotherapy […]

no male and female brain types

What would it mean for there to be a “male brain” or a “female brain”? Human genitals are mostly easy to categorise just by sight as either male or female. It makes sense to talk about there being different male and female types of genitals. What would it mean for the same to be true […]

Sex differences in brain size

Next time someone asks you “Are men and women’s brains different?”, you can answer, without hesitation, “Yes”. Not only do they tend to be found in different types of bodies, but they are different sizes. Men’s are typically larger by something like 130 cubic centimeters. Not only are they actually larger, but they are larger […]

neurotransmitter fashion

A graph of scientific articles published per year which mention four major neurotransmitters in their title: What I take from this is Dopamine is king! And with great popularity, comes great misrepresentation. What happened to glutamate research in the mid 1990s? The recent hype about oxytocin doesn’t seem to be driven by a spike in […]

hormones, brain and behaviour, a not-so-simple story

There’s a simple story about sex differences in cognition, which traces these back to sex differences in early brain development, which are in turn due to hormone differences. Diagrammatically, it looks something like this: Cordelia Fine’s “Delusions of Gender” (2010) accuses both scientists and popularisers of science with being too ready to believe overly simple, […]

A group of researchers at Baylor College of Medicine evaluated 94 patients aged 18 to 85 years who had been hospitalized for mild, moderate, or severe traumatic brain injury (TBI). […]

Neuroeconomics – Capitalisation on Consumer Control?

In an attempt to explain the internal processes governing the occurrences in the economic world, neuroeconomics is an emerging interdisciplinary field attempting to merge psychology and economic theory. Simply put, the biological basis of behavioral economics; how and why people make judgements and decisions with economic consequences in terms of simple cerebral biology. But why […]

Sex differences in cognition are small

Lately I’ve been thinking about sex differences in brain and cognition. There are undeniable differences in the physical size of the brain, and different brain areas, even if there are no ‘female’ and ‘male’ brains categorically. These physical differences do not translate directly into commensurate differences in cognition. Indeed, there is support for a ‘gender […]

Boost Confidence with Brain Training

Confidence is an attractive and necessary quality to succeed in business, relationships, and life. But, it is a subjective and, sometimes, misunderstood characteristic. From the painfully shy to the arrogantly over-confident, what makes people think and feel what they think and feel about themselves? The authors of a new study report that they have uncovered […]
