As of , one in fourteen adult black males was incarcerated in prison or jail on any given day, representing a doubling of this rate from Furthermore, a black male born in has a 29 percent chance of spending time in prison at some point in his life. However, with the War on Drugs in the s, African American arrest rates skyrocketed, while white arrest rates increased only slightly. By the end of the s, African Americans were more than five times more likely than whites to be arrested for drug-related offenses. Instead these crime statistics reflect the government's targeting of only specific types of drug use and trafficking. Alexander claims that racial beliefs and stereotypes as a direct result of a media saturated with images of black criminals have obviously and predictably created a sharp disparity in the rates at which blacks and whites are subject to encounters with law enforcement. From to , the rate of white women in prisons and jails went up from 27 per , to 76 per , However, the rate of black women in prisons and jails went up from per , to per ,Neuroscience Abstract A precise fear memory encoding a traumatic event enables an individual to avoid danger and identify safety.
Something Scary
An impaired fear memory contextual amnesiahowever, puts the individual at risk of developing posttraumatic stress disorder PTSD due to the inability to identify a safe context when encountering trauma-associated cues later in life. Although it is gaining attention that contextual amnesia is a critical etiologic factor for PTSD, there is no treatment currently available that can reverse contextual amnesia, and whether such treatment can prevent the development of PTSD is unknown.
Here, we report that I a single dose of transcranial photobiomodulation PBM applied immediately after tone fear conditioning can reverse contextual amnesia. II A single dose of PBM applied after memory recall can reduce contextual fear during both contextual and cued memory testing.

IV Finally, we report that fear extinction was facilitated when PBM was applied in the early intervention window of memory consolidation. Our results demonstrate that PBM treatment applied immediately after a traumatic event or its memory recall can protect contextual fear memory and prevent the development of PTSD-like psychopathological fear in rats. Download PDF Introduction Experiencing a traumatic event leads to the formation and then consolidation of several types of fear-influenced memories, including context-associated and cue-associated memories, each of which triggers the expression of fear [ 1 The Dangers Of Racism: Fear Of The Unknown, 2 ]. While creating and retrieving these memories is essential for avoiding danger and identifying safety [ 34 ], an improper balance in the strength of these memories can lead to psychopathological fear states [ 1Unknoen ].
Individuals with developing posttraumatic stress disorder PTSD are well-known for having an intrusive cued memory cued hypermnesia that paradoxically coexists with an impaired contextual memory contextual amnesia [ 56789 ]. Contextual amnesia indicates that individuals developing PTSD cannot remember Danggers dangerous context where and when the traumatic event originally occurred [ 1 ].
In contrast, cued hypermnesia indicates that individuals developing PTSD cannot correctly identify the trauma-associated cue in a safe context after memory recall [ 110 ]. Despite living in a safe environment, repeated encounters with trauma-associated cues lead to cued memory retrieval outside of the dangerous context, and eventually, the cued memory becomes pathogenic [ 111 Unkmown, 12 ].

This implies that protecting the integrity of the contextual memory encoding the dangerous context is the key to the differentiation of a safe context referred to as context discriminationthereby inhibiting cued-elicited fear in the safe context and facilitating the process of fear extinction, a weakened fear response following non-reinforced exposure to a conditioned stimulus [ 13 ].
The process of context discrimination depends on hippocampal input [ 1415 ] because the hippocampus is essential for the formation and recollection of episodic and contextual memories of past events [ 111617 ]. The inability to appropriately perform context or cue discrimination in animals is referred to as PTSD-like memory impairments and has been manifested previously in rodent models [ 118 ].
Robust evidence has confirmed that stress hormones, including norepinephrine and glucocorticoids, released shortly after experiencing a traumatic event, can facilitate memory consolidation and form long-term memories [ 4 ]. However, the high level of corticosterone in the hippocampus, originating either from external perfusion or prolonged restraint following fear conditioning training with strong foot shock, is considered an inducer of contextual amnesia [ 118 ].
Although contextual amnesia is gaining attention as a critical etiologic factor for PTSD, there is no treatment currently available that can reverse contextual amnesia. Whether such treatment can prevent the development of cued hypermnesia is unknown. Photobiomodulation PBM is a non-invasive physical therapy in which low energy near-infrared light is applied to a tissue of interest and has been demonstrated to produce complex treatment effects for diverse diseases, including several brain disorders [ 1920 ].
PBM has also been investigated as a potential treatment for psychiatric disorders, both in animal studies and human pilot trials. Using a prolonged stress model to induce a More info phenotype in rats, the application of PBM to acupoints in both legs reduced anxiety-like symptoms and increased neural activation at the anterior cingulate cortex [ 21 ]. In Te clinical pilot trials, transcranial PBM reduced depressive symptoms and demonstrated safety in human patients with major depressive disorder [ 2223 ].
In a study examining the effects of transcranial PBM on generalized anxiety disorder, patients treated with PBM displayed significant reductions in measures of anxiety symptoms and had improvements in their quality of sleep [ 24 ]. It is thought that the underlying mechanism mediating these effects is, in part, related to the ability of PBM to promote mitochondrial function and beneficial trophic factor release by way of Racis:m cytochrome c oxidase activity [ 25 ]. Cytochrome c oxidase has been identified as the primary target of PBM treatment [ 192627 ].]
Certainly. And I have faced it. Let's discuss this question.
