Pressbox (Press Release) - 428, P = 0.521; tone: F1,18 = 26.7, P <0.0001; genotype�� tone: F1,18 = 2.71, P = 0.117; Fig. 6D). Also foreground contextual fear (as assessed upon re-exposure to the conditioning context) showed the same intensity tuclazepam and specificity (as assessed by comparing freezing in the conditioning context and freezing before tone presentation in the test context) in the two genotypes (genotype: F1,18 = 2.00, P = 0.173; context: F1,18 = 57.0, P <0.0001; genotype��context: F1,18 = 0.32, P = 0.581). Although the similarities in sensitized fear speak against genotype differences in tone and shock perception, we additionally measured in other animals' ASRs to stimuli of increasing intensity and their modulation by PPs. We failed to observe differences in ASR (genotype: F1,16 = 0.303, P = 0.590; intensity: F4,64 = 36.2, P <0.0001; genotype��intensity: F4,64 = 0.488, P = 0.744; Fig. 6E). In addition, mice showed the same PP facilitation and PPI with a PP intensity of 65 selleckchem dB and interpulse intervals smaller or greater than 25 milliseconds (genotype: F1,16 = 0.0, P = 0.983; interpulse interval: F4,64 = 23.6, P <0.0001; genotype��interpulse interval: F4,64 = 0.287, P = 0.885; Fig. 6F). Results with PP intensities of 55 and 75 dB showed essentially the same findings and are omitted for the sake of clarity and brevity. Together, these findings support a modulatory role of CNGA3 channels for the formation of the tone-shock association in the amygdala. It has been shown that nitric oxide (NO)/cGMP signaling can support synaptic plasticity and consolidation of memory via stimulation of the cGMP-dependent protein kinase I (cGKI) (Feil & Kleppisch 2008; Kleppisch et al. 2003; Ota et al. 2008; Paul et al. 2008). In the present study, we report expression of the cone-type Angiogenesis inhibitor CNGA3 channel in mouse amygdala and hippocampus. Although the level of expression was found to be very low, the observed localization of CNGA3 in neuronal fibers suggests a role of this ion channel in synaptic function. Cyclic nucleotide-gated channels represent alternative targets for regulation by cGMP and may, thus, also contribute to the regulation of fear memory formation and related synaptic plasticity. Heteromeric CNG channels containing the CNGA3 subunit are ideally suited to control these functions as they are activated by low micromolar concentrations of cGMP, do not inactivate and are highly permeable for calcium ions (Biel et al. 1994; Frings et al. 1995). Here, we show that CNGA3-containing channels are critically involved in the regulation of synaptic plasticity in the hippocampus. It is well established that LTP in the CA1 region of the hippocampus is triggered by postsynaptic Ca2+ entry mediated principally by N-methyl-d-aspartate (NMDA) receptors (Lynch 2004; Malenka & Nicoll 1999). One could, therefore, assume that CNGA3 channels expressed postsynaptically in hippocampal pyramidal cells might support the induction of LTP.
