   Sep 7, 2022 · Hippocampus damage can affect memory and learning-related functions. For example, brain injury survivors with hippocampus damage may struggle to recall old memories or create new ones. Fortunately, this structure of the brain has a unique ability to heal and improve overall function by creating new brain cells through a process called neurogenesis.

   Hippocampus. The hippocampus is a part of your brain that’s responsible for your memory and learning. This small structure helps you remember, both short- and long-term, and gain awareness from your environment. The hippocampus is at risk of injury or damage from underlying conditions like Alzheimer’s disease. Contents Overview Function ...

   Hippocampus is an area of the brain vital for functions such as learning, memory and mood [1,2]. It is also one of the brain regions that reacts to injury or neurodegeneration with robust plasticity [3–7].

   Feb 9, 2016 · The high prevalence of memory deficits after injury point to a relative vulnerability of the hippocampus and mesial temporal structures as compared to the rest of the brain (Hamm et al., 1993; Finset et al., 1999; Comper et al., 2005), and electrophysiologic studies have shown that changes occur in hippocampal circuit excitability after TBI ...

   Acutely after TBI, and in particular for the fluid-percussion brain injury model, there is a large increase in intracellular calcium in the cortex and hippocampus that lasts for up to 4 days . These global changes in calcium signaling through glutamate excitotoxicity and potassium depolarization waves stimulate several calcium-dependent cell ...

   Is the hippocampus vulnerable to brain injury?

   • Previous studies have found that the hippocampus is highly vulnerable to brain injury, in both experimental models of TBI and during human TBI.

   What percentage of the hippocampus is affected by a traumatic brain injury?

   • Atrophy of the hippocampus averages approximately only 10–15% in chronic TBI survivors [ 12, 17, 19 ]. However, lesion studies have found that a loss of at least 20–30% of the dorsal hippocampus and at least 39–52% of the ventral hippocampus is required to begin to observe impairments in hippocampal-dependent learning tasks [ 44 ].

   What happens to the hippocampus after a head injury?

   • Although often not directly mechanically injured by the head injury, in the weeks to months following TBI, the hippocampus undergoes atrophy and exhibits deficits in long-term potentiation (LTP), a persistent increase in synaptic strength that is considered to be a model of learning and memory.

   Oct 18, 2022 · The hippocampus is a small, curved formation located deep in the temporal lobe of the brain. As part of the limbic system, the hippocampus has three primary functions: forming new memories, learning, and emotions. It is susceptible to damage from injury, stress, and disease, including psychiatric and neurological conditions such as Alzheimer's ...
