Abstract

A growing number of advanced neuroimaging studies have been used to evaluate the nature of consciousness. Such studies have focused on various states of consciousness as well as ways of inducing altered states of consciousness. Various states of consciousness include the normal waking state, sleep states, the brain under anesthesia, and the impact of disorders such as seizures or schizophrenia. The induction of altered states of consciousness includes practices such as meditation or the use of psychoactive substances leading to psychedelic effects. This paper reviews some of the relevant research and then considers some of limitations and challenges for studying consciousness with neuroimaging, particularly via positron emission tomography (PET), single photon emission computed tomography (SPECT), and advanced magnetic resonance imaging (MRI) modalities.

神经成像和意识：PET， SPECT和高级MRI模式的应用。

越来越多先进的神经影像学研究被用于评估意识的本质。这些研究集中在意识的各种状态以及诱导意识状态改变的方法上。意识的各种状态包括正常的清醒状态、睡眠状态、麻醉下的大脑以及癫痫发作或精神分裂症等疾病的影响。意识状态改变的诱导包括冥想或使用导致迷幻效果的精神活性物质等做法。本文回顾了一些相关研究，然后考虑了利用神经成像研究意识的一些局限性和挑战，特别是通过正电子发射断层扫描（PET）、单光子发射计算机断层扫描（SPECT）和先进的磁共振成像（MRI）模式。
