Improved structural and functional brain imaging technologies provide assistance in understanding brain gender differences. A Japanese study of the effects of age and gender has been recently published in Human Brain Mapping. The study focussed on brain gray and white matter volumes in a variety of brain regions. Gray matter volumes declined with age in both genders. In the younger subjects,

Computational model sheds light on how the brain recognizes objects
Researchers have developed a new mathematical model to describe how the human brain visually identifies objects. The model accurately predicts human performance on certain visual-perception tasks, which suggests that it's a good indication of what actually happens in the brain, and it could also help improve computer object-recognition systems.

How does the human brain memorize a sound?
Sound repetition allows us to memorize complex sounds in a very quick, effective and durable way. According to new research, this form of auditory learning is believed to occur in daily life to help us identify and memorize sound patterns; it allows, for example, immediate recognition of sounds which become familiar through experience, such as the voice of relatives. The same mechanism is involve

New role for zebrafish in human studies
A researcher has discovered that zebrafish -- an important animal model in disease and environmental studies -- could provide the means to help scientists eventually reveal the function of a mysterious enzyme linked to the steroid cortisol, and found in the human brain.

First Physiological Evidence Of Brain’s Response To Inequality
The human brain is a big believer in equality - and a team of scientists from the California Institute of Technology (Caltech) and Trinity College in Dublin, Ireland, has become the first to gather the images to prove it. Specifically, the team found that the reward centers in the human brain respond more strongly when a poor person receives a financial reward than when a rich person does...

A Tale of Two Studies: Voxel-Based Lesion-Symptom Mapping
Brain imaging has contributed greatly to our understanding of the functional neuroataomy of the human brain. A lot these contributions have been blogged about by my bestest buddy Neuroskeptic (why don't you return my phone calls anymore!?). One of the more popular methods used to capture brain function is the functional magnetic resonance (fMRI). However, the results of fMRI studie

Dolphin cognitive abilities raise ethical questions, says Emory neuroscientist
Many modern dolphin brains are significantly larger than those of humans and second in mass to the human brain when corrected for body size, says a scientist. Some dolphin brains exhibit features correlated with complex intelligence, including a large expanse of neocortical volume that is more convoluted than that of humans, extensive insular and cingulated regions, and highly differentiated cell
