How neuronal recognition of songbird calls unfolds over time
A novel computational approach sheds new light on the response of neurons in the brain of a songbird when it hears and interprets the meaning of another bird's call.

Can excessive athletic training make your brain tired? New study says yes
You'd expect excessive athletic training to make the body tired, but can it make the brain tired too? A new study suggests that the answer is 'yes.'
Read moreHow neural circuits form in a developing embryo
A new imaging method follows young neurons in a developing embryo as they progress from a messy jumble of cells into a coordinated control center. The approach lets scientists track development and emerging cell function simultaneously across entire circuits.
Read moreHow neural circuits drive hungry individuals to peak performance
Success is no accident: To reach your goal you need perseverance. But where does the motivation come from? Scientists have now identified the neural circuit in the brain of fruit flies which makes them perform at their best when searching for food.
Read moreDo children's brains really get thinner?
The brains of young children get thinner as they grow. At least that's what scientists used to believe. For decades, the debate has been about how and why that happens. Now neuroscientists suggest that it may be partly an illusion.
Read moreBlood-brain barrier damage occurs even with mild head trauma
In a new study of adolescent and adult athletes, researchers have found evidence of damage to the brain's protective barrier, without a reported concussion.
Read moreHow and why does Parkinson's disease effect women and men differently?
There is growing evidence that Parkinson's disease (PD) affects women and men differently. In this insightful review, scientists present the most recent knowledge about these sex-related differences and highlight the significance of estrogens, which play an important role in the sex differences in PD.
Read moreBrain anatomy changes with maturation to adolescence
In a first-of-its-kind study, researchers piece together a road map of typical brain development in children during a critical window of maturation.
Read moreBiological clock influences immune response efficiency
The biological clock influences immune response efficacy. Indeed, CD8 T cells, which are essential to fight infections and cancers, function very differently according to the time of day.
Read moreHow people with psychopathic traits control their 'dark impulses'
How do people with psychopathic traits control their 'dark impulses?' A team of researchers are finding answers in levels of gray matter density in the ventrolateral prefrontal cortex, a region of the brain involved in the regulation of emotions, including fear and anger.
