What these activations indicate is that, often, a traumatized brain is "bottom-heavy," meaning that activations of lower, more primitive areas, including the fear center, are high, while higher areas of the brain (also known as cortical areas) are underactivated. In other words, if you are traumatized, you may experience chronic stress, vigilance, fear, and irritation. You may also have a hard time feeling safe, calming down, or sleeping. These symptoms are all the result of a hyperactive amygdala.

Further psycasts can be gained by using a Psytrainer which grants the specific psycast mentioned in their name. Additional psycasts are available for purchase from traders, with Empire bases and traders having the most, and tribals having the least. A psycaster can learn any number of psycasts through psytrainers, up to and including every psycast in the game and limited only by the availability of psytrainers themselves.N.b. if using a psytrainer for a level higher than the current psylink level of the user, the learned psycast will replaced the one usually gained for that level when that level is acheived. Given using the psytrainer after gaining that level either grants an additional power or does not work and thus does not consume the psytrainer, it is always best to only use psytrainers after the required psylink level has been achieved.
Psyfocus is a special type of mental structuring which is necessary to use psychic powers. Psyfocus dissipates over time, and must be built by regular meditation. Losing all psyfocus makes someone unable to use psychics, but has no other consequences. Higher levels of psyfocus permit higher-level powers, but also increase the rate of psyfocus dissipation
Many meditation foci can be improved by having other buildings in its radius. For example, a sculpture can be improved by having other, high quality sculptures in its radius. Conversely, most natural foci are weakened by nearby artificial structures.
Depression is a common, disabling condition for which psychological treatments are recommended. Behavioural activation has attracted increased interest in recent years. It has been over 5 years since our meta-analyses summarised the evidence supporting and this systematic review updates those findings and examines moderators of treatment effect.
Randomised trials of behavioural activation for depression versus controls or anti-depressant medication were identified using electronic database searches, previous reviews and reference lists. Data on symptom level and study level moderators were extracted and analysed using meta-analysis, sub-group analysis and meta-regression respectively.
The results in this meta-analysis support and strengthen the evidence base indicating Behavioural Activation is an effective treatment for depression. Further high quality research with longer term follow-up is needed to strengthen the evidence base.
Depression is the most common mental disorder in community settings [1] and recent predictions state that by 2030 it will be the leading cause of disease burden in high-income countries [2]. NICE [1] promote the use of cognitive behavioural therapy (CBT) combining both behavioural and cognitive techniques. More recently a meta-analysis has suggested equivalence across most psychotherapies for depression [3]. If this is the case the idea of parsimony, using the least complex but acceptable theoretically derived treatment, may offer considerable benefit in terms of stability and distribution of the chosen intervention.
In this updated review we found that behavioural activation for depression is clinically effective. With the increased interest in BA over previous years such an update was needed as our previous reviews were conducted over 5 years ago [5], [6]. This current review includes 26 studies which is a clear increase over the 16/17 included in those previous reviews. In addition this current update addresses some of the gaps identified in those reviews (BA vs. medication). We found BA to be superior to controls across 31 comparisons in 25 studies and small but significant short term superiority to antidepressant medication.
We explored the association between the types of participant recruited and the effect size of the intervention in three subgroup comparisons. We could find no difference in effect between recruitment groups (general adult, older adult, student, post natal) nor if a diagnostic interview had been used in studies, although statistical power to detect differences between subgroups was low. We did however find a larger effect size in studies that had higher baseline depression severity. In addition the setting within which recruitment was conducted and the processes used to identify participants did not moderate the effect size of BA.
A number of limitations exist to this review. Whilst we were able to include a reasonable number of studies it is of note that many were small and of poor quality. The median sample size in the BA arms were 11 and 16 for controls and medication groups, with ranges of 4 to 56 and 9 to 50 respectively. This links directly to the quality of the studies, there were a significant amount of older studies which generally were not subject to the same level of quality standards as those conducted in recent years. Rather than exclude such studies we chose to include them and deal with quality issues via subgroup and sensitivity analysis. Whilst study quality was not associated with effect size when BA was compared to controls it is of note that only seven studies of the 26 included met three or more commonly accepted standards for RCTs. Study quality appears to be improving over time with those seven studies being generally the most recently conducted however the publication of further high quality studies is needed to improve confidence in these findings. In contrast when poor quality studies were excluded in the BA comparison to medication analysis, the significance of the effect in favour of BA disappeared. This suggests that results found in this comparison must be viewed with caution due to the limited numbers of studies and participants included in the review. We focus mainly on depression outcomes post treatment as only five studies include follow up data beyond 6 months. Some other studies do report longer term follow up for BA that appears promising [38] however comparisons are with other active therapeutic interventions, not control participants, and as such did not meet our inclusion criteria. Our analysis of follow up data vs. control interventions indicates a medium effect size between six and nine months however further research is required examining the longer term benefits of BA. Seventeen of the 26 included studies were conducted in the United States (US) and whilst we could observe no difference between the effect sizes between those inside and outside the US this should be considered in the interpretation of results. The key argument linked to the dissemination of BA is the durability within wider dissemination and whilst we were able to conduct the first exploration of this in meta-analysis from a clinical perspective the linked question of cost utility requires more research.
Despite limitations, our updated meta-analysis provides evidence that supports BA as an effective treatment for depression with outcomes at least as effective as anti-depressant medication. We have found early indications supporting the implementation of the intervention beyond the traditional psychotherapy workforce. Further, individually fully powered and high quality trials are needed to test BA in terms of low cost implementation and the cost effectiveness this may offer. We are aware of at least one large scale randomised controlled trial currently underway to answer these questions [91].

A number of studies link eating certain foods with keeping the brain healthy and suggest that other foods can increase health risk. For example, high-fat and high-sodium foods can lead to health problems, such as heart disease and diabetes, that can harm the brain.
Figure 7.5 illustrates the two major types of heterosynaptic plasticity; presynaptic inhibition and presynaptic facilitation. Presynaptic inhibition is not an esoteric phenomenon. It is very prominent in the spinal cord and regulates the propagation of information to higher brain centers. An action potential in the presynaptic cell produces an EPSP in the postsynaptic cell. The modulatory cell (M1) makes an axoaxonic synapse with the presynaptic cell. After firing cell M1, the EPSP in the postsynaptic cell is smaller. This phenomenon is called presynaptic inhibition, because cell M1 regulates the ability of the presynaptic cell to release transmitter. The modulatory transmitter engages metabotropic-type receptors that activate a second messenger system that phosphorylates Ca2+ channels in such a way that the Ca2+ channels open less readily. Fewer Ca2+ channels are opened with a subsequent action potential in Pre and therefore the Ca2+ influx (ICa) will be reduced. Less Ca2+ influx leads to less transmitter release and a smaller EPSP. 2ff7e9595c
