We investigated the modulatory effects of serotonin on the tuning of 114 neurons in the central nucleus of the inferior colliculus (ICc) of Mexican free-tailed bats and how serotonin-induced changes in tuning influenced responses to complex signals. We obtained a "response area" for each neuron, defined as the frequency range that evoked discharges and the spike counts evoked by those frequencies at a constant intensity. We then iontophoretically applied serotonin and compared response areas…

Serotonin Shifts First-Spike Latencies of Inferior Colliculus Neurons
- Biology, PsychologyThe Journal of Neuroscience
- 2005
The results support the general conclusion that changes in latency are an important part of the neuromodulatory repertoire of serotonin within the auditory system and show that serotonin can change latency either in conjunction with broad changes in other aspects of neuronal excitability or in highly specific ways.
Serotonin modulates responses to species-specific vocalizations in the inferior colliculus
- Biology, PsychologyJournal of Comparative Physiology A
- 2005
The effects of iontophoretically applied serotonin on the responses of individual inferior colliculus neurons to a variety of recorded species-specific vocalizations were examined and it was found that a functional consequence of these serotonin-evoked changes would be to change the population response to species- specific vocalizations.
Serotonin 1B receptor modulates frequency response curves and spectral integration in the inferior colliculus by reducing GABAergic inhibition.
- BiologyJournal of neurophysiology
- 2008
In vivo extracellular recording and iontophoresis of the selective 5-HT1B agonist CP93129 were used to characterize inhibition within and surrounding frequency response curves using two-tone protocols to indirectly measure inhibition as a decrease in spikes relative to an excitatory tone alone, consistent with the reduction of GABAA-mediated inhibition by 5- HT1B receptors in the IC.

The features revealed by whole-cell recordings show that the processing in many IC cells results from inputs spectrally broader and more complex than previously believed.

The results suggest that the population activity evoked by a particular sound is not simply a consequence of the hard wiring that connects the IC to lower and higher regions but rather is highly dynamic because of the functional reconfigurations induced by serotonin and almost certainly other neuromodulators as well.

Serotonergic induction of IPSCs was observed primarily in young animals and thus may represent a mechanism for amplifying the activity of inhibitory synapses in LSO during a period of use-dependent plasticity in postnatal development.

The response of the MSO in the free-tailed bat is created by a complex interaction of inhibition and excitation, and the data confirm an earlier speculation about this interdependence based on data accessed from a gerbil brain slice preparation.

There is no study in birds investigating the distribution of 5-HT fibers in the auditory pathway, and the authors believe this to be a cause for concern.
