It is becoming increasingly clear that advancements in genetics and neuroscience are leading toward direct methods of mind control. An array of hi-tech methods have been announced – magnetic manipulation via “neural dust,”  high-powered lasers, and using light beamed from outside the skull. As a result, scientists are making bold claims that they can alter the brain even to the extent of turning off consciousness altogether.

But it is memory research that might be among the most troubling. As I’ve previously stated in other articles, our memories help us form our identity: who we are relative to where we have been. Positive or negative lessons from the past can be integrated into our present decisions, thus enabling us to form sound strategies and behaviors that can aid us in our quest for personal evolution. But what if we never knew what memories were real or false? What if our entire narrative was changed by having our life’s events restructured? Or what if there were memories that were traumatic enough to be buried as a mechanism of sanity preservation, only to be brought back to us in a lab?

We’ve already witnessed research into the erasure of memories, the implantation of false memories, and triggering memories of fear when none previously existed. (Source) MIT researchers are now claiming to have found the specific brain switch that links emotions to memory. Once again, the temptation of helping those who have experienced trauma might open doors to very unethical applications.

I’ve highlighted and commented on some of the key areas in the MIT press release below which, to me, illustrate a clear potential for erasing many of the memories that we often associate with building strength of character, or could aid in our future development – morally, ethically, and spiritually. This research threatens to create a race of happy zombies devoid of natural emotion if a proper ethical framework is not established. In fact, much like the happy pills of Big Pharma, MIT admits that these findings could lead not only to direct intervention via manipulation of brain cells through light, but a new class of drugs to treat Post Traumatic Stress Disorder.

However, notice the very first example: bullying. I’ll admit that this can be stressful and perhaps traumatic for some, but where would one draw the line? Anyone who receives an insult or hurt feelings just takes a pill or laser blasts the memory away? It’s also a path toward literally erasing history. How about victims of torture? Sure, who wants to remember that, but what if scientists could erase that memory, thus eliminating future testimony against those committing such atrocities?

Most memories have some kind of emotion associated with them: Recalling the week you just spent at the beach probably makes you feel happy, while reflecting on being bullied provokes more negative feelings.

A new study from MIT neuroscientists reveals the brain circuit that controls how memories become linked with positive or negative emotions. Furthermore, the researchers found that they could reverse the emotional association of specific memories by manipulating brain cells with optogenetics — a technique that uses light to control neuron activity.

The findings, described in the Aug. 27 issue of Nature, demonstrated that a neuronal circuit connecting the hippocampus and the amygdala plays a critical role in associating emotion with memory. This circuit could offer a target for new drugs to help treat conditions such as post-traumatic stress disorder, the researchers say.

“In the future, one may be able to develop methods that help people to remember positive memories more strongly than negative ones,” says Susumu Tonegawa, the Picower Professor of Biology and Neuroscience, director of the RIKEN-MIT Center for Neural Circuit Genetics at MIT’s Picower Institute for Learning and Memory, and senior author of the paper.

The paper’s lead authors are Roger Redondo, a Howard Hughes Medical Institute postdoc at MIT, and Joshua Kim, a graduate student in MIT’s Department of Biology.

Shifting memories

Memories are made of many elements, which are stored in different parts of the brain. A memory’s context, including information about the location where the event took place, is stored in cells of the hippocampus, while emotions linked to that memory are found in the amygdala.

Previous research has shown that many aspects of memory, including emotional associations, are malleable. Psychotherapists have taken advantage of this to help patients suffering from depression and post-traumatic stress disorder, but the neural circuitry underlying such malleability is not known.

In this study, the researchers set out to explore that malleability with an experimental technique they recently devised that allows them to tag neurons that encode a specific memory, or engram. To achieve this, they label hippocampal cells that are turned on during memory formation with a light-sensitive protein called channelrhodopsin. From that point on, any time those cells are activated with light, the mice recall the memory encoded by that group of cells.

Last year, Tonegawa’s lab used this technique to implant, or “incept,” false memories in mice by reactivating engrams while the mice were undergoing a different experience. In the new study, the researchers wanted to investigate how the context of a memory becomes linked to a particular emotion. First, they used their engram-labeling protocol to tag neurons associated with either a rewarding experience (for male mice, socializing with a female mouse) or an unpleasant experience (a mild electrical shock). In this first set of experiments, the researchers labeled memory cells in a part of the hippocampus called the dentate gyrus.

Two days later, the mice were placed into a large rectangular arena. For three minutes, the researchers recorded which half of the arena the mice naturally preferred. Then, for mice that had received the fear conditioning, the researchers stimulated the labeled cells in the dentate gyrus with light whenever the mice went into the preferred side. The mice soon began avoiding that area, showing that the reactivation of the fear memory had been successful.

The reward memory could also be reactivated (think social engineering – N.W.): For mice that were reward-conditioned, the researchers stimulated them with light whenever they went into the less-preferred side, and they soon began to spend more time there, recalling the pleasant memory.

A couple of days later, the researchers tried to reverse the mice’s emotional responses. For male mice that had originally received the fear conditioning, they activated the memory cells involved in the fear memory with light for 12 minutes while the mice spent time with female mice. For mice that had initially received the reward conditioning, memory cells were activated while they received mild electric shocks (trauma-based mind control – N.W.).

Next, the researchers again put the mice in the large two-zone arena. This time, the mice that had originally been conditioned with fear and had avoided the side of the chamber where their hippocampal cells were activated by the laser now began to spend more time in that side when their hippocampal cells were activated, showing that a pleasant association had replaced the fearful one. This reversal also took place in mice that went from reward to fear conditioning.

Altered connections

The researchers then performed the same set of experiments but labeled memory cells in the basolateral amygdala, a region involved in processing emotions. This time, they could not induce a switch by reactivating those cells — the mice continued to behave as they had been conditioned when the memory cells were first labeled.

This suggests that emotional associations, also called valences, are encoded somewhere in the neural circuitry that connects the dentate gyrus to the amygdala, the researchers say. A fearful experience strengthens the connections between the hippocampal engram and fear-encoding cells in the amygdala, but that connection can be weakened later on as new connections are formed between the hippocampus and amygdala cells that encode positive associations.

“That plasticity of the connection between the hippocampus and the amygdala plays a crucial role in the switching of the valence of the memory,” Tonegawa says.

These results indicate that while dentate gyrus cells are neutral with respect to emotion, individual amygdala cells are precommitted to encode fear or reward memory. The researchers are now trying to discover molecular signatures of these two types of amygdala cells. They are also investigating whether reactivating pleasant memories has any effect on depression, in hopes of identifying new targets for drugs to treat depression and post-traumatic stress disorder.

David Anderson, a professor of biology at the California Institute of Technology, says the study makes an important contribution to neuroscientists’ fundamental understanding of the brain and also has potential implications for treating mental illness. (What is mental illness? We’ve heard increasing discussion about how conspiracy theories and independent thinking – Oppositional Defiant Disorder – might need treatment.)

“This is a tour de force of modern molecular-biology-based methods for analyzing processes, such as learning and memory, at the neural-circuitry level. It’s one of the most sophisticated studies of this type that I’ve seen,” he says.

The research was funded by the RIKEN Brain Science Institute, Howard Hughes Medical Institute, and the JPB Foundation.
