Bat and Bird Songs for Systems Neuroscience

This week’s Science features an article about the songs of bats – not the ultrasonic echolocating calls most often associated with these wonderful creatures but complex vocalizations that bats use socially. The most well-studied “songsters,” as the author, Virginia Morell, calls them, are songbirds. In species like canaries, zebra finches and starlings, the male sings a courtship song that he… Read more →

Coordination Between Motor and Sensory Systems

One interesting problem in systems neuroscience is how the nervous system’s motor output interacts with its sensory systems. Sensory inputs that result from motor commands must be either filtered out or used to guide future motor actions. In other words, the organism must distinguish between sensory inputs that are self-generated and those from the outside world. In the juvenile songbird,… Read more →

Milk Does Not Cause Autism

The radical organization whose supposed mission is to protect animal welfare now says that cow milk not only worsens autistic symptoms but can actually cause autism too. PETA’s campaign to stop people from using animal products latched on to obscure studies of dietary influences on autistic symptoms. A PETA blog post refers to two studies that found a link between… Read more →

Using the Brain to Treat the Body’s Diseases

There’s an article in New York Times Magazine about using electrical signals in the nervous system to signal to the rest of the body to somehow alter molecular signaling outside the nervous system. Neuroscientists have known for a while that neurons transmit messages by electro-chemical signals: at each synapse, an electrical impulse arrives from a cell body, is converted to… Read more →

Connectomic Reconstruction of Direction-Selective Circuit in the Retina

Connectomics is the area of neuroscience that aims to collect and curate the entirety of the connections made by all neurons in a brain (the product being called a “connectome”). For the human brain, that would be a data set of 100 billion neurons, each of which is estimated to make 1000-10000 synapses with other neurons (on the order of… Read more →

Oklahoma’s Torture-execution

With the world in shock over the botched execution of Clayton Lockett in Oklahoma last week, rather than questioning the morality of capital punishment, we should reevaluate America’s prison system as a whole. With an ever-growing population of inmates, America’s prisons are operating under the arcane notion that punishment deters crimes, while ignoring a growing body of scientific work that… Read more →

Congress to Peer Review Science Funding?

There is a bill circulating in the House of Representatives, sponsored by Lamar Smith of Texas, that aims to give Congress the power of oversight over government grants for scientific research. Grants from the National Science Foundation are given out to basic research projects based on their scientific merit, as determined by a system of peer review. Lamar Smith’s legislature… Read more →

The President’s BRAIN Initiative

At three pounds, 100 billion cells, 10,000 as many connections, the human brain makes Facebook look like child’s play of a network, not without reason: our brains are solely responsible for our every thought, emotion and action. The human brain is the most complicated machine in the known universe. It is fitting then, that President Obama announced this week that the state of our knowledge of brain function… Read more →
