&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&amp;#039;&amp;#039;&amp;#039;Activation-synthesis hypothesis&amp;#039;&amp;#039;&amp;#039; is a [[neurobiological]] theory proposed by [[J. Allan Hobson]] and [[Robert McCarley]] in 1977, which suggests that dreams are a result of the brain&amp;#039;s attempt to interpret random neural activity during [[REM sleep]].&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
The activation-synthesis hypothesis proposes that the initial randomness of [[REM sleep]] is generated in the [[brainstem]], particularly in the [[pons]], where many of the signals originate. These signals are then sent to the [[cerebral cortex]], which attempts to synthesize and interpret them, resulting in the experience of dreaming.&lt;br /&gt;
&lt;br /&gt;
== Process ==&lt;br /&gt;
The process begins with the activation of the [[neurotransmitter]] systems in the brainstem, including the [[acetylcholine]] system. This activation leads to the random firing of neurons, which the cerebral cortex then attempts to interpret and make sense of. The result is a dream, which can often seem bizarre or nonsensical due to the random nature of the neural activity.&lt;br /&gt;
&lt;br /&gt;
== Criticisms ==&lt;br /&gt;
While the activation-synthesis hypothesis has been influential in the field of [[dream research]], it has also been subject to criticism. Some researchers argue that it does not account for the often meaningful and coherent nature of dreams. Others suggest that it does not explain why we remember some dreams but not others.&lt;br /&gt;
