Objective : the studies indicate that the "eye-blink" components of "acoustic startle reflex" can be modulated through emotionally slide stimuli. Pleasant stimulants reduce eye-blink amplitude, whereas unpleasant stimulants enhance them. Method: the present study examines the modulation of the acoustic startle reflexes through a short film clips (2-min), classified as pleasant, unpleasant and...
Glycine receptors (GlyR) belong to the pentameric ligand-gated ion channel (pLGIC) superfamily and mediate fast inhibitory transmission in the vertebrate CNS. Disruption of glycinergic transmission by inherited mutations produces startle disease in man. Many startle mutations are in GlyRs and provide useful clues to the function of the channel domains. E103K is one of few startle mutations foun...
Defects in glycinergic synaptic transmission in humans, cattle, and rodents result in an exaggerated startle reflex and hypertonia in response to either acoustic or tactile stimuli. Molecular genetic studies have determined that mutations in the genes encoding the postsynaptic glycine receptor (GlyR) α1 and β subunits (GLRA1 and GLRB) and the presynaptic glycine transporter GlyT2 (SLC6A5) are t...
Movement disorders are a prominent and common feature in many autoantibody-associated neurological diseases, a group of potentially treatable conditions that can mimic infectious, metabolic or neurodegenerative disease. Certain movement disorders are likely to associate with certain autoantibodies; for example, the characteristic dyskinesias, chorea and dystonia associated with NMDAR antibodies...
OBJECTIVE The primary goal of this study was to identify clinical risk factors, in addition to muscle weakness, for upper-extremity hypertonia in patients with severe ischaemic supratentorial stroke. The secondary goal was to investigate the time course of upper-extremity hypertonia in these patients during the first 26 weeks post-stroke. DESIGN Inception cohort. PATIENTS Forty-three consec...
OBJECTIVE The primary goal was to identify the neuroradiological and neurophysiological risk factors for upper-extremity hypertonia in patients with severe ischaemic supratentorial stroke. DESIGN Inception cohort. PATIENTS Forty-three consecutive patients with an acute ischaemic supratentorial stroke and an initial upper-extremity paralysis admitted to an academic hospital recruited over a ...
Congenital hyperekplexia is a rare, potentially treatable neuromotor disorder. Three major genes of effect are known, and all three affect glycinergic neurotransmission. Two genes encode for subunits of the postsynaptic inhibitory glycine receptor, GLRA1 encoding the α1 subunit and GLRB encoding the β subunit. The third, SLC6A5, encodes the cognate presynaptic glycine transporter 2. Ninety-seve...
