Optically analyzing local brain environment: Astrocytes' acid response in epileptic mice

-
Researchers have shown that astrocytes in the mouse brain exhibit an acid response with intensified epileptic seizures. The astrocytes' acid response could lead to the amplification of excitatory neuronal signals and be the underlying drive for generating plasticity for epileptogenesis.

Lengthened consonants mark the beginning of words

-
Resim
Speech consists of a continuous stream of acoustic signals, yet humans can segment words from each other with astonishing precision and speed. To find out how this is possible, a team of linguists has analysed durations of consonants at different positions in words and utterances across a diverse sample of languages. They have found that word-initial consonants are, on average, around 13 milliseconds longer than their non-initial counterparts. The diversity of languages for which this effect was found suggests that this might be a species-wide pattern -- and one of several key factors for speech perception to distinguish the beginning of words within the stream of speech. http://dlvr.it/TDdxVF

Study of former NFL players finds 1 in 3 believe they have CTE

A study of nearly 2,000 former NFL players shows one-third believe that they have chronic traumatic encephalopathy (CTE). Those individuals were more likely to report cognitive symptoms, and 25% of them also reported suicidal thoughts. The players who thought they had CTE also were more likely to have low testosterone, depression, pain and other treatable conditions that cause cognitive symptoms. http://dlvr.it/TDbTFK
