murraya koenigii l. (rutaceae), commonly known as curry leaf tree, closely associated with south india where the word “curry” originates from the tamil “kari” for spiced sauces. curry leaves are a rich source of carbazole alkaloids which possess various biological activities such as antitumor, antioxidant and anti-inflammatory. curry leaf has a potential role in the treatment of diabetes. reser...

A prevailing theory regarding the evolution of language implicates a gestural stage prior to the emergence of speech. In support of a transition of human language from a gestural to a vocal system, articulation of the hands and the tongue are underpinned by overlapping left hemisphere dominant neural regions. Behavioral studies demonstrate that human adults perform sympathetic mouth actions in ...

Simple actions, such as rhythmic tongue protrusions, forelimb facial strokes, and forelimb flails, are emitted by rats both during taste-elicited ingestion/aversion and during postprandial grooming. This study combined peripheral trigeminal deafferentation with a computer-assisted video analysis of action form to examine the use of cutaneous feedback from the face in action production. Changes ...

Discussion Sibilants are produced in the sibilant slot between the tongue apex and the palatal surface of upper incisors. Sigmatism was observed, as one might expect, with different orthodontic anomalies, when there were severe protrusions or tremata present. In these cases the function of the tongue is impaired and consequently sigmatism occurs. The results of the presented study might be nega...

The present study investigated the protective effect of the ethanolic extract of Psidium guajava L. against tacrine-induced orofacial dyskinesia in rats. Behavioral assessments such as vacuous chewing movements, tongue protrusions, orofacial bursts, locomotion, and cognition were recorded. Forebrain of tacrine treated animals was assessed for its antioxidant levels. P. guajava (100 and 200 mg/k...

Effect of methanolic extract of Hibiscus rosa sinensis (100-300 mg/kg) was studied on reserpine-induced orofacial dyskinesia and neurochemical alterations. The rats were treated with intraperitoneal reserpine (1 mg/kg, ip) for 3 days every other day. On day 5, vacuous chewing movements and tongue protrusions were counted for 5 min. Reserpine treated rats significantly developed vacuous chewing ...

Sophisticated tongue movements contribute to speech and mastication. These movements are regulated by communication between the bilateral cortex and each tongue side. The functional connection between the cortex and tongue was investigated using oscillatory interactions between whole-head magnetoencephalographic (MEG) signals and electromyographic (EMG) signals from both tongue sides during hum...

An eight-year-old boy with Angelman-(Happy Puppet-)Syndrome is described. Nearly all typical symptoms of the syndrome, especially severe psychomotoric retardation with spontaneous outbursts of laughing and protrusions of the tongue, athetoid movements, typical electroencephalogram and microcephaly, could be found in our patient. The incidence of the Angelman-syndrome may be underestimated.

Tongue movements contribute to oral functions including swallowing, vocalizing, and breathing. Fine tongue movements are regulated through efferent and afferent connections between the cortex and tongue. It has been demonstrated that cortico-muscular coherence (CMC) is reflected at two frequency bands during isometric tongue protrusions: the beta (β) band at 15-35Hz and the low-frequency band a...
