The growing realization that electrical coupling is present in the mammalian brain has sparked renewed interest in determining its functional significance and contrasting it with chemical transmission. One question of interest is whether the two types of transmission can be selectively regulated, e.g., if a cell makes both types of connections can electrical transmission occur in the absence of...

In the Aplysia mechanoafferent B21, afferent transmission is in part regulated via the control of active spike propagation. When B21 is peripherally activated at its resting membrane potential, spikes fail to propagate to an output process, and afferent transmission does not occur. In this report we show that the propagation failure is in part a result of the fact that the somatic region of B21...

In a recent Cognition paper (Cognition 85 (2002) B21), Bornkessel, Schlesewsky, and Friederici report ERP data that they claim "show that online processing difficulties induced by word order variations in German cannot be attributed to the relative infrequency of the constructions in question, but rather appear to reflect the application of grammatical principles during parsing" (p. B21). In th...

We are studying afferent transmission from a mechanoafferent, B21, to a follower, B8. During motor programs, afferent transmission is regulated so that it does not always occur. Afferent transmission is eliminated when spike propagation in B21 fails, i.e., when spike initiation is inhibited in one output region-B21's lateral process. Spike initiation in the lateral process is inhibited by the B...

A protocol has been developed to distinguish between wild-type, heterozygous and homozygous oim mutant mice. Oim mice (The Jackson Laboratory, Bar Harbor, ME, USA) have a singlebase deletion in their proα2(I) collagen gene (cola-2 gene). This mutation changes the reading frame at the 3′ end of the mRNA causing synthesis of an altered C-propeptide that ultimately inhibits association of these mo...

The chicken major histocompatibility complex (MHC) has strong genetic associations with resistance and susceptibility to certain infectious pathogens. The cell surface expression level of MHC class I molecules varies as much as 10-fold between chicken haplotypes and is inversely correlated with diversity of peptide repertoire and with resistance to Marek's disease caused by an oncogenic herpesv...

The buccal ganglion of Aplysia contains a heterogeneous population of peptidergic, radula mechanoafferent (RM) neurons. To investigate their function, two of the larger RM cells (B21, B22) were identified by morphological and electrophysiological criteria. Both are low-threshold, rapidly adapting, mechanoafferent neurons that responded to touch of the radula, the structure that grasps food duri...

Abstract Booth ( Solar Phys. 296 , 108, 2021; hereafter B21) is essentially a critique of the Hilbert transform techniques used in our paper (Leamon et al., 295 36, 2020; L20) to predict termination solar cycles. Here we respond his arguments; methodology and parameter choices do extract mathematically robust signature terminators from historical sunspot record. We agree that attempt L20 extrap...

HLA class I antigen distribution of Sikh population from Punjab is presented. A total of 404 individual of Sikh community who were either donors for renal transplant recipients or staff in PGIMER Chandigarh were selected. HLA class I antigens (A and B) were identified using the standard National Institute of Health two stage micro lymphocytotoxicity assay. The phenotypic frequencies of HLA-A10 ...
