Abstract

A new spike discrimination procedure addressing the specific problem of spike superposition is described. The method, based on a shift-invariant wavelet transform and its amplitude-and-phase representation, has the advantage of both reducing the effect of noise present in the data and correcting the latency of specific components in a waveform. When spikes overlap and produce unknown patterns, the procedure extracts the constituent spikes and also estimates their exact time of occurrence. Fast implementation algorithms, having complexity of at most O (N log N), allow the use of the method in real-time applications.

Substantia gelatinosa neurons in the medullary dorsal horn: An intracellular labeling study in the rat.

Morphologic features and electrical membrane properties of neurons in the substantia gelatinosa (SG) of the caudal spinal trigeminal nucleus (the medullary dorsal horn; MDH) were examined in the rat. Intracellular recording and biocytin-injection combined with histochemical staining were performed in horizontal slices. Twenty-four SG (lamina II) neurons were recorded stably and stained successfully. Both projection neurons (PNs; n = 9) that sent axons to regions outside the MDH and intrinsic neurons (INs; n = 15) that sent axons only to the MDH were observed. The INs were divided into those with dense axonal arborization (INDAs; n = 7) and those with sparse axonal arborization (INSAs; n = 8). In the PNs, the dendrites with spines spread to all MDH layers (laminae I-III). The main axons sent collaterals within the SG and rostrally, caudally, or medially to laminae I and III of the MDH, interpolar spinal trigeminal nucleus, spinal tract of the trigeminal nerve, or upper cervical cord segments. In the INDAs, the dendrites arising from the rostral and caudal pole of the cell bodies mainly extended rostrally and caudally parallel to the rostrocaudal axis of the SG: the dendritic trees were elongated and oval in shape and were confined within the SG. The axonal field of each INDA, a dense mesh of axonal processes, was elongated and oval in shape and almost was confined within the SG. In the INSAs, a small, round cell body was located in the center of each dendritic field, which usually was limited within the SG. Axonal processes ran radially to spread to all layers of the MDH, constituting round or oval axonal fields. The three groups of SG neurons showed more or less different intracellular responses to current injections. In particular, adaptation of spike frequency, hyperpolarizing sag, and rebound excitation were observed in the PNs and INSAs but not in the INDAs. Slow ramp depolarization and slow afterdepolarization were recorded only in INDAs.

GABAergic and non-GABAergic spiking interneurons of local and intersegmental groups in the crayfish terminal abdominal ganglion.

In the first step toward identifying the neurotransmitter released from spiking interneurons of both local and intersegmental groups in the crayfish terminal abdominal ganglion, the authors examined whether spiking local interneurons and ascending intersegmental interneurons contain the transmitter gamma-aminobutyric acid (GABA). In this paper, 17 identified ascending interneurons and three spiking local interneurons were stained by intracellular injection of Lucifer yellow and subsequently treated for immunocytochemical staining against GABA. Double-labeling experiments revealed that six identified ascending interneurons are GABAergic, but no spiking local interneurons show GABA-like immunoreactivity. Four ascending interneurons with GABA-like immunoreactivity (reciprocal closing ascending neuron 5 [RC-5], reciprocal opening ascending neuron 6 [RO-6], variable-effect ascending interneuron 1 [VE-1], and no-effect ascending interneuron 4[NE-4]) had cell bodies that formed a cluster on the ventral surface of the rostral edge of the ganglion, whereas two GABAergic interneurons (coinhibiting ascending interneuron 2 [CI-2] and NE-2) had cell bodies in a caudal region around the cell body of the seventh flexor inhibitor (FI) motor neuron. Another four rostral interneurons (RC-2, RC-3, RC-4, and NE-3) and seven caudal interneurons (CI-3, RC-7, RO-1, RO-2, RO-3, RO-4, and NE-1) had no GABA-like immunoreactivity. Because VE-1 is known to make direct inhibitory connections with other ascending interneurons, whereas RC-3 and RO-1 are known to make direct excitatory connections, the immunocytochemical results from this study are consistent with previous physiological studies. Although many spiking local interneurons (including spiking local interneuron 1 of the anterior group [sp-ant1]) made direct inhibitory connections with nonspiking local interneurons, three spiking local interneurons (sp-ant1, spiking local interneuron 6 of the medial group [sp-med6], and spiking interneuron 5 of the posterior group [sp-post]) do not show GABA-like immunoreactivity. These results suggest that the inhibitory transmitter released from spiking local interneurons is not GABA but that another substance mediates the inhibitory action of these interneurons. J. Comp.

Correlation of miniature synaptic activity and evoked release probability in cultures of cortical neurons.

Spontaneous miniature synaptic activity is caused by action potential (AP)-independent release of transmitter vesicles and is regulated at the level of single synapses. In cultured cortical neurons we have used this spontaneous vesicle turnover to load the styryl dye FM1-43 into synapses with high rates of miniature synaptic activity. Automated selection procedures restricted analysis to synapses with sufficient levels of miniature activity-mediated FM1-43 uptake. After FM1-43 loading, vesicular FM1-43 release in response to AP stimulation was recorded at single synapses as a measure of release probability. We find that synapses with high rates of miniature activity possess significantly enhanced evoked release rates compared with a control population. Because the difference in release rates between the two populations is [Ca(2+)](o)-dependent, it is most likely caused by a difference in release probability. Within the subpopulation of synapses with high miniature activity, we find that the probabilities for miniature and AP-evoked release are correlated at single synaptic sites. Furthermore, the degree of miniature synaptic activity is correlated with the vesicle pool size. These findings suggest that both evoked and miniature vesicular release are regulated in parallel and that the frequency of miniature synaptic activity can be used as an indicator for evoked release efficacy.
