We determined honeydew production by male and female sweetpotato whiteflies and the effects of temperature on honeydew production of each sex. We also determined honeydew production by each nymphal instar. Overall, adult SPW produced more honeydew than nymphs. Adult females produced more honeydew than males. The relative differences between honeydew production for males and females and between ...

When monitoring neural activity using intracranial electrical recordings, researchers typically consider the signals to have two primary components: fast action potentials (APs) from neurons near the electrode, and the slower local field potential (LFP), thought to be dominated by postsynaptic currents integrated over a larger volume of tissue. In general, a decrease in signal power with increa...

Sharp waves (SPWs) occur in the hippocampal EEG during behaviours such as alert immobility and slow-wave sleep. Despite their widespread occurrence across brain regions and mammalian species, the functional importance of SPWs remains unknown. Experiments in the present study indicate that long-term potentiation (LTP) is significantly impaired in slices, prepared from the temporal aspect of rat ...

Neuronal activities in superficial (II and III) and deep (V and VI) layers of the entorhinal cortex (EC) are preferentially modulated by theta and sharp wave (SPW) EEG, respectively. We investigated the possibility that distinct EEG patterns represent optimal stimulus patterns for induction of long-term potentiation (LTP) in different layers of the EC. We examined effects of three different sti...

The characteristic, behaviour-related network oscillations of the mammalian hippocampus (, gamma and ripples) are accompanied by strongly phase-coupled action potentials in specific subsets of GABAergic interneurones. It has been suggested that the resulting phasic, repetitive inhibition shapes rhythmic coherent activity of the neuronal network. Here, we examined whether synaptic inhibition ent...

During slow-wave sleep (SWS) following periods of spatial activity, hippocampal place cells that were temporally correlated, by virtue of the overlap of their place fields, exhibit enhanced temporal correlations, even though the animal sleeps in a different location (Wilson and McNaughton [1994] Science 267:676-679). The discharge of cells with overlapped place fields is more correlated in subs...

Brewing is found to be one of the lucrative businesses in Nigeria. The brewer’s yeast commonly known as Saccharomyces cerevisiae always imported and its price affects products drastically. In this work, strain was isolated from Palm Wine, identified used an alternative beer brewing. isolate (SPW) seen poses many similar characteristics (SCT) foreign countries. enriched employed laboratory for p...

Sweetpotato weevils (SPWs) can cause up to 100% yield losses in sweetpotato (Ipomoea batatas). Nevertheless, there has been limited success breeding for SPW resistance globally. This is attributed partly difficulty screening because the complex and mediated by several indicators. Measuring all these indicators costly time consuming. To enhance efficiency selection resistance, need profile ident...

1. The study of the physiological role of long-term potentiation (LTP) is often hampered by the challenge of finding a physiological event that can be used to assess synaptic strength. We explored the possibility of utilising a naturally occurring event, the hippocampal sharp wave (SPW), for the assessment of synaptic strength and the induction of LTP in vivo. 2. We used two methods in which hi...
