Summary
Astrocytes regulate synapse and circuit formation in the developing mammalian cerebral cortex. This study overviews neuronal and astrocytic development, highlighting astrocyte roles in synapse maturation and distinct circuit establishment.
Area of Science:
- Neuroscience
- Developmental Biology
- Cell Biology
Background:
- Mammalian cerebral cortex neurons form complex circuits crucial for brain function.
- Astrocytes, a type of glial cell, are key regulators of synapse development and function.
- Neuronal synapse formation follows astrocyte generation and neuronal branching in cortical development.
Purpose of the Study:
- To provide an overview of synapse and circuit formation in the rodent cortex.
- To emphasize the developmental timelines of both neuronal and astrocytic maturation.
- To discuss the role of astrocytes in synapse formation and the establishment of cortical circuits.
Main Methods:
- Review of existing literature on cortical development.
- Analysis of developmental timelines for neurons and astrocytes.
- Examination of astrocyte-synapse interactions and synapse-related proteins.
Main Results:
- Synapse formation is concurrent with neuronal branching and astrocyte maturation.
- Astrocytes play a critical role in regulating synapse formation and function.
- Astrocyte-synapse contact and specific proteins are involved in forming distinct cortical circuits.
Conclusions:
- Astrocytes are essential for the proper development of cortical circuits.
- Understanding astrocyte roles provides insight into brain development and function.
- Further research into astrocyte-synapse interactions can elucidate circuit formation mechanisms.

02:47The Synapse
133.7K
Neurons communicate with one another by passing on their electrical signals to other neurons. A synapse is the location where two neurons meet to exchange signals. At the synapse, the neuron that sends the signal is called the presynaptic cell, while the neuron that receives the message is called the postsynaptic cell. Note that most neurons can be both presynaptic and postsynaptic, as they both transmit and receive information.

01:29Econometric Views (EViews)
594
Econometric Views, often stylized as EViews, is a package that merges statistical analysis with econometric studies. It is designed to provide tools for time series analysis, forecasting, and econometric model simulation. The software originated from MicroTSP software and has evolved significantly since its inception in 1981. The history of EViews is marked by a continuous effort to enhance its computational speed and user interface. It was initially developed for large computing systems but...

Electrical synapses found in all nervous systems play important and unique roles. In these synapses, the presynaptic and postsynaptic membranes are very close together (3.5 nm) and are actually physically connected by channel proteins forming gap junctions.
Gap junctions allow the current to pass directly from one cell to the next. In contrast, in the chemical synapse, the neurotransmitters carry the information through the synaptic cleft from one neuron to the next. They consist of two...

11.9K
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

01:27Cranial Bones: Lateral View
4.6K
The lateral view of the cranium is dominated by temporal, sphenoid, and ethmoid bones.
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
