nervous system
abnormal synaptic plasticity ( J:317639 )
• short-term plasticity is altered by accentuating short-term depression
abnormal synaptic depression ( J:317639 )
• hippocampal neurons show more pronounced short-term depression
• the deeper short-term depression is not associated with changes in evoked release during burst stimuli
decreased paired-pulse ratio ( J:317639 )
• hippocampal neurons show reduced paired-pulse ratio with a more pronounced short-term depression
• however, spontaneous neurotransmitter release in glutamatergic hippocampal neurons is unaltered
