Innovative 'mini-brains' could revolutionize Alzheimer's treatment

-
New research could revolutionize the way Alzheimer's and other brain-related diseases are diagnosed and treated -- by building tiny brains in a petri dish.

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

Revealing the neuronal pathways involved in adaptive decision-making in primates

-
Resim
Neuronal pathways originating from the orbitofrontal cortex (OFC) of the brain participate in different adaptive behaviors, but which pathways are used for distinct adaptive strategies remains unclear. In a recent study, researchers from Japan conducted behavioral experiments on monkeys whose OFC pathways could be selectively silenced chemically. Findings demonstrate how these independent pathways are linked to experience-based adaptation and knowledge-based adaptation in primates. http://dlvr.it/TDTv5k
