Locusts reveal how neurons distinguish multiple odors

(Medical Xpress)—Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action. However, there is often more than one odor in the environment, such ...

Neural networks learn to link temporally dispersed stimuli

Rustling leaves, a creaking branch: To a mouse, these sensory impressions may at first seem harmless - but not if a cat suddenly bursts out of the bush. If so, they were clues of impending life-threatening danger. Robert ...

Deciphering the cellular reading system of DNA methylation

(Medical Xpress)—Scientists from the FMI identify how a family of proteins reads the methylation marks on the DNA so critical for cell development. These MBD proteins bind directly to methylation marks and inactivate the ...

Preemie-born parents linked to children with autism

In a study of medical registry records of nearly 400,000 parent-child pairs from Denmark, a Yale School of Public Health study found that parents who were themselves born very prematurely were nearly twice as likely to have ...

Anesthesia changes neuronal choreography

Even under deep anesthesia, nerve cells remain highly active. A study conducted by researchers from Charité - Universitätsmedizin Berlin has shown by high-resolution cellular imaging that local neuronal networks remain ...
