Neurons, the cells of the nervous system, communicate by transmitting chemical signals to each other through junctions called synapses. This synaptic transmission is critical for the brain and the spinal … Continue Reading Optogenetics used to capture neuronal transmission in the live mammalian brain.
Some neurons are more active than others, even when they are positioned right next to each other and are one and the same neuron type. Researchers from the Max Delbrück … Continue Reading Broad receptive field identified in multi-level neuronal activity.
Researchers from Boston Children’s Hospital and Massachusetts Institute of Technology have developed a targeted drug-delivery system that’s based on a combination of ultraviolet (UV) light and short, single strands of DNA … Continue Reading Researchers use DNA paired with light to deliver drugs on target.
With the aid of new methods, a research team at Karolinska Institutet have developed a detailed map of the networks of the brain that control the neurotransmitter serotonin. The study, … Continue Reading Discovery of new pathways controlling the serotonergic system.
Researchers at Johns Hopkins have mapped the sound-processing part of the mouse brain in a way that keeps both the proverbial forest and the trees in view. Their imaging technique … Continue Reading New mapping approach lets scientists zoom in and out as the brain processes sound.
Until recently, available microscopes were too slow to capture a beating heart in 3D. Now, a team from the Max Planck Institute has developed a high-speed, selective plane illumination microscope … Continue Reading Max Planck scientists image a beating heart in 3D.
The human body produces substances, called endocannabinoids, that work in a similar way to cannabis. These endocannabinoids may not produce a ‘high’, but are of tremendous importance for the functioning … Continue Reading Increased levels of the body’s own cannabinoids impair embryonic brain development.
A new study by researchers at the University of Oregon published in the journal Neuron describes a brainstem circuit in mice that may help explain how active movement impacts the … Continue Reading Oregon study details brain pathways linking visual function, running.
