We demonstrate the use of the gene gun to introduce fluorescent dyes, such as DiI, into neurons in brain slices from rodents and non-human primates of different ages. In this particular case, we use adult mice (3-6 months old) and adult cynomologus monkeys (9-15 years old). This technique, originally described by the laboratory of Dr. Lichtman (Gan et al., 2000), is well suited for the study of dendritic branching and dendritic spine morphology and can be combined with traditional...

This protocol describes a simple method for isolating and culturing primary mouse cerebral granule neurons (CGNs) from 6-7 day old pups, efficient transduction of CGNs for loss and gain of function studies, and modelling NMDA-induced neuronal excitotoxicity, low-potassium-induced cell death, DNA-damage, and oxidative stress using the same culture model.
FAQs
Spatial summation combines signals arriving at different synaptic locations, whereas temporal summation reflects the combined effect of inputs arriving over time. Each process can shift the membrane potential toward or away from the threshold for action-potential initiation. Considering both forms helps explain how a developing neuron evaluates simultaneous activity and changing patterns of synaptic input.
Excitatory inputs move the membrane potential toward action-potential threshold, while inhibitory inputs shift it away from threshold. Their balance determines how readily a neuron responds to combined synaptic activity. During development, examining this relationship helps researchers understand how neural circuits refine communication rather than allowing either excitation or inhibition to dominate functional signaling.
The cell body and axon initial segment are key locations where the effects of synaptic inputs are evaluated before an electrical response begins. Signals integrated there influence whether the membrane potential reaches the threshold for action-potential initiation. Their involvement provides a useful cellular framework for relating synaptic connectivity to the output of a developing neuron.
As neurons grow, their synaptic connections are refined, and integration provides a way to assess the functional consequences of that refinement. Changes in the combined excitatory and inhibitory input can alter whether a neuron approaches action-potential threshold. Studying these effects connects structural changes in developing circuits with the emergence of coordinated neural communication.
Patterns of integration can show how developing neurons establish an effective balance between excitation and inhibition while their circuits mature. Because the combined inputs influence electrical responses, they provide information about whether growing connections support functional communication. This makes neuron integration a framework for linking synaptic development with the progressive organization of the nervous system.
Developmental disorders that disrupt neural connectivity may also alter how excitatory and inhibitory signals are combined. Examining the resulting effects on membrane potential and action-potential threshold can help relate abnormal connections to impaired circuit function. This subject therefore supports research that connects developmental changes in synaptic organization with disturbances in neural communication.
