Brain's reward circuit activity ebbs and flows with a woman's hormonal cycle
... system circuitry includes: the prefrontal cortex, seat
of thinking and planning; the amygdala, a fear center; the hippocampus, a learning and memory hub; and the striatum, which relays signals from these areas to the cortex. Reward circuit neurons harbor receptors for estrogen and progesterone. However,...
Scientist-astronaut sends T-cells into space
...ch was made to fit precisely under the cosmonaut's seat
in the Soyuz spacecraft. Kubik contains a compartment for weightless experiments as well as a centrifuge that can accelerate cells in a range from 0.2 to 2 earth gravities. On board the space station, European Space Agency astronaut-scientist Thoma...
Cortex matures faster in youth with highest IQ
...d with age, particularly in the prefrontal cortex, seat
of abstract reasoning, planning, and other "executive" functions. The smartest 7-year-olds tended to start out with a relatively thinner cortex that thickened rapidly, peaking by age 11 or 12 before thinning. In their peers with average IQ, an initia...
Infants can organise visual information at just four months
...rouping experiments, each baby was placed in a car seat
facing a screen onto which images were projected. Overhead cameras recorded how long each infant looked at images on the screen. The infants were shown an array where the stimuli were arranged by similarity in either horizontal lines or vertical colu...
Nano-Probes Allow an Inside Look at Cell Nuclei
...cent labels. This could give biologists a ringside seat
to nuclear processes that span several hours or days, such as DNA replication, genomic alterations, and cell cycle control. The long-lived probes may also allow researchers to track the effectiveness of disease-fighting drugs that target these proces...
Highly adaptable genome in gut bacterium key to intestinal health
...its outer surface, B. theta is able to hold onto a seat
at the table. The bacterium also produces the necessary utensils to break different types of carbohydrate chains into 'bite-sized' pieces; the utensils are a variety of enzymes directed at different types of carbohydrates." When a set of germ-free m...
