The faculty of language: what is it, who has it, and how did it evolve?

by Marc D Hauser , Noam Chomsky , W Tecumseh Fitch - Science, , 2002
"... We argue that an understanding of the faculty of language requires substantial interdisciplinary cooperation. We suggest how current developments in linguistics can be profitably wedded to work in evolutionary biology, anthropology, psychology, and neuroscience. We submit that a distinction should ..."

be made between the faculty of language in the broad sense (FLB) and in the narrow sense (FLN). FLB includes a sensory-motor system, a conceptual-intentional system, and the computational mechanisms for recursion, providing the capacity to generate an infinite range of expressions from a finite set

Muftuler T. Auditory-motor interaction revealed by fMRI: speech, music, and working memory in area Spt

by Gregory Hickok, Bradley Buchsbaum, Colin Humphries, Tugan Muftuler - J Cogn Neurosci
"... & The concept of auditory – motor interaction pervades speech science research, yet the cortical systems supporting this interface have not been elucidated. Drawing on exper-imental designs used in recent work in sensory – motor integration in the cortical visual system, we used fMRI in an effor ..."
Abstract - Cited by 93 (7 self) - Add to MetaCart
MRI in an effort to identify human auditory regions with both sensory and motor response properties, analogous to single-unit responses in known visuomotor integration areas. The sensory phase of the task involved listening to speech (nonsense sentences) or music (novel piano melodies); the ‘‘motor’ ’ phase

Attempts to Physiologically class ^ Human Thenar Motor Units

by C. K. Thomas, R. S. Johansson, B. Bigland-ritchie
"... I. This study was designed to determine whether human thenar motor units can be classified into types by the same physiological criteria used for other mammalian limb motor units and to con-sider whether such classification is functionally relevant. 2. Contractile responses of 25 human thenar single ..."

Effects of Aging on Genioglossus Motor Units in Humans

by Julian P. Saboisky, Daniel W. Stashuk, Andrew Hamilton-wright, John Trinder, Sanjeev Nandedkar Atul
"... The genioglossus is a major upper airway dilator muscle thought to be important in obstructive sleep apnea pathogenesis. Aging is a risk factor for obstructive sleep apnea although the mechanisms are unclear and the effects of aging on motor unit remodeled in the genioglossus remains unknown. To ass ..."

R and Bigland-Ritchie B. Motor-unit discharge rates in maximal voluntary contractions of three human muscles

by F. Bellemare, J. J. Woods, R. Johansson, B. Bigland-ritchie, Summary A N D Conclusions - J Neurophysiol , 1983
"... 1. Single motor-unit firing rates have been recorded during maximal voluntary contrac-tions using tungsten microelectrodes. Over 300 units from four subjects were sampled from each of three muscles. These were the biceps brachii, adductor pollicis, and soleus, chosen because of known differences in ..."
Abstract - Cited by 28 (3 self) - Add to MetaCart
brachii and adductor pollicis agreed well with the mean values reported for human fast-twitch motor units, while those for soleus fell in the range observed for human slow-twitch units. 5. An argument is presented that suggests that, in response to voluntary effort, the range of discharge rates of each

Motor unit substitution in longduration contractions of the human trapezius muscle

"... long-duration contractions of the human trapezius muscle. J. Neuro-physiol. 82: 501–504, 1999. We examined the activity pattern of low-threshold motor units in the human trapezius muscle during contractions of 10 min duration.
