Parkinson's disease (PD) is characterized by a range of motor symptoms. Besides the
cardinal symptoms (akinesia and bradykinesia, tremor and rigidity), PD patients show …

The structure of the brain and the nature of evolution suggest that, despite its uniqueness,
language likely depends on brain systems that also subserve other functions. The …

What are the psychological, computational and neural underpinnings of language? Are
these neurocognitive correlates dedicated to language? Do different parts of language …

Our use of language depends upon two capacities: a mental lexicon of memorized words
and a mental grammar of rules that underlie the sequential and hierarchical composition of …

During the first two years of human life a common neural substrate (roughly Broca's area)
underlies the hierarchical organization of elements in the development of speech as well as …

FOR THE PAST 200 YEARS, virtually all attempts to account for the neural bases and the
evolution of human language have focused on the neocortex. And in the past 40 years …

In a stimulating synthesis of cognitive science, anthropology, and linguistics, Philip
Lieberman tackles the fundamental questions of human nature: How and why are human …

Human speech involves species-specific anatomy deriving from the descent of the tongue
into the pharynx. The human tongue's shape and position yields the 1: 1 oral-to-pharyngeal …

Communication impairment is common in Parkinson's disease (PD) and may have both
motor speech control and cognitive-linguistic underpinnings. The neurobiology of …

The traditional theory equating the brain bases of language with Broca's and Wernicke's
neocortical areas is wrong. Neural circuits linking activity in anatomically segregated …
