Document Summary
Information can be transmitted between two neurons when : how can transmittion be stopped? the pre-synaptic membrane (sender) releases nt into the synaptic cleft: and the nt binds to certain receptors on the post-synaptic membrane (receiver) Reverbatory circuits: what would happen if there were only excitatory connections in reverbatory circuits, seizure. Its dynamic range is, therefore: 10log10(100/5) = ~13 decibels (db): but we can sense differences in stimuli (e. g. , light, sound) over much greater dynamic ranges than 13 db! For example, you can hear over a dynamic range of well over 90 db! How can this be achieved if any one neuron"s dynamic range is so small: answer: neural coding, neurons evolved to have specializations beyond a linear current to rate process associated with ap production. Just as anatomists have long classified neurons by the shapes of their dendritic trees, so cellular neurophysiologists may come to recognize classes of neuronal computational styles.
