A fundamental characteristic of neurons that extend into the skin and record touch, so-called first-order neurons in the tactile system, is that they branch in the skin so that each neuron reports touch from many highly-sensitive zones on the skin.
According to researchers at the Department of Integrative Medical Biology, IMB, Umeå University, this branching allows first-order tactile neurons not only to send signals to the brain that something has touched the skin, but also process geometric data about the object touching the skin.
Our work has shown that two types of first-order tactile neurons that supply the sensitive skin at our fingertips not only signal information about when and how intensely an object is touched, but also information about the touched object’s shape, says Andrew Pruszynski, who is one of the researchers behind the study.
The study also shows that the sensitivity of individual neurons to the shape of an object depends on the layout of the neuron’s highly-sensitive zones in the skin.
Perhaps the most surprising result of our study is that these peripheral neurons, which are engaged when a fingertip examines an object, perform the same type of calculations done by neurons in the cerebral cortex. Somewhat simplified, it means that our touch experiences are already processed by neurons in the skin before they reach the brain for further processing, says Andrew Pruszynski.
Medical Examiner In Zimmerman Trial Sues For $100M, Claims Prosecution Threw Case
In a bombshell allegation, Florida medical examiner Dr. Shiping Bao (pictured) claims that Florida state prosecutors were biased against Trayvon Martin and purposely threw the case, and he is suing the state for $100 million, reports WFTV.com.
According to Bao, the medical examiner, state attorney’s office, and Sanford Police Department all felt that Martin “got what he deserved.” Bao also claims that he received the strong, though subtle, message not to speak on certain things:
“He was in essence told to zip his lips. ‘Shut up. Don’t say those things,’” said Bao’s legal counsel, legendary Attorney Willie Gary.
Bao’s allegations come swiftly on the heels of him being fired from his position as associate medical examiner.
Volusia County released a letter on Tuesday, stating that Bao was fired last week. Spokesman Dave Byron declined to give a reason for Bao’s termination, citing “county standard personnel practices,” reports CBS News.
you go medical examiner Bao, you go!
