Summary
New neurons in the hippocampus are generated throughout life and impact memory. Targeting these cells may offer new treatments for temporal lobe epilepsy.
Area of Science:
- Neuroscience
- Cell Biology
- Epilepsy Research
Background:
- Adult neurogenesis, the generation of new neurons, occurs in the human hippocampus throughout life.
- These newly generated dentate granule cells play a role in memory formation.
- Dysregulation of hippocampal neurogenesis is implicated in the pathology of temporal lobe epilepsy (TLE).
Purpose of the Study:
- To review the evidence for adult neurogenesis in the human hippocampus.
- To discuss the role of new neurons in memory and TLE.
- To explore the therapeutic potential of targeting adult neurogenesis for epilepsy.
Main Methods:
- Review of preclinical rodent studies on adult neurogenesis and epilepsy.
- Analysis of existing literature on hippocampal neurogenesis and its functions.
- Synthesis of findings from studies investigating interventions targeting new neurons in epilepsy models.
Main Results:
- Consistent generation of dentate granule cells throughout human lifespan, including old age.
- Established role of adult-generated neurons in hippocampal memory functions.
- Emerging preclinical evidence suggests that modulating adult neurogenesis can alter epilepsy pathogenesis.
Conclusions:
- Adult hippocampal neurogenesis is a conserved process in humans with implications for cognitive function.
- Targeting adult-generated neurons presents a promising novel therapeutic strategy for temporal lobe epilepsy.
- Further research into manipulating neurogenesis could lead to disease-modifying epilepsy treatments.

01:24Epilepsy and Seizures: Overview
1.2K
Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

01:15Neurogenesis and Regeneration of Nervous Tissue
1.6K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

01:33Adult Stem Cells
33.4K
Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

14.8K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

01:15Development of the Lymphatic System
2.0K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
