- Spastic paralysis (resulting from the failure of muscles to relax), induced by the neurotoxin strychnine, occurs when this poison blocks the binding of: the excitatory neurotransmitter acetylcholine to post-synaptic sodium channels the excitatory neurotransmitter glutamate to post-synaptic calcium channels the excitatory neurotransmitter serotonin to post-synaptic potassium channels the inhibitory neurotransmitter glycine to post-synaptic chloride channels the inhibitory neurotransmitter melatonin to post-synaptic bicarbonate channelsarrow_forwardFollowing administration of an opiate drug, "pain signals" are prevented from getting out of the spinal cord via two mechanisms. One inhibits spinal cord neurons that communicate with the parafascicular nucleus of the thalamus. What is the other way that pain signals are stopped? dendro-dendritic synapses that enhance IPSI's in somatosensory neurons. the disinhibition of long axons that start in the spinal cord and influence free nerve endings directly. O a feedback loop to the periaquedictal grey of the midbrain, which enhances neural activity in that area. axo-axonic synapses that prevents somatosensory neurons from releasing neurotransmitter.arrow_forwardTemporal summation refers to: summation of action potentials in the temporal cortex. summation of postsynaptic potentials on a neuron occurring closely together in time. summation of postsynaptic potentials at different places on a neuron at the same time. summation of postsynaptic potentials in the temporal cortex.arrow_forward
