I think the point of wanting a control is still valid. Science always benefits from having a control

[14] found that all three approaches could in principal achieve such specificity. However, because brain tissue is conductive, it can be challenging to confine neuronal activation by traditional electrical stimulation to a single cortical column. In contrast, optogenetic stimulation can be applied with high spatial specificity (e.g. by delivering light via a 200um fiber optic apposed to the cortex) and with cell-type specificity (e.g. excitatory or inhibitory cells); however, optogenetics requires viral vectors and gene transduction procedures, making it less easy for human applications [15]. Over the last decade, infrared neural stimulation (INS), which is a pulsed heat-mediated approach, has provided an alternative method of neural activation. Because brain tissue is 75% water, infrared light delivered near peak absorption wavelengths (e.g. 1875 nm [16]) permits effective delivery of heat to the brain tissue. In particular, experimental and modelling studies [[17], [18], [19]] have shown that 1875 nm light (brief 0.5sec trains of 0.25msec pulses forming a bolus of heat) effectively achieves focal (submillimeter to millimeter sized) activation of neural tissue Does NIRS -based (neuro-) imaging induce neuronal growth? Are there better photonic beam-forming apparatuses than TI DLP projectors with millions of tiny actuated mirrors; isn't that what a TV does? Cold plasma also affects neuronal regrowth and could or should be used for wound closure. Are they cold plasma-ing Sam (Hedlund) in "Tron: Legacy" (2010) before the disc golf discus thing? Does cold plasma reduce epithelial scarring? A certain duration of cold plasma also appears to increase seed germination rate FWIW. To find these studies, I used a search engine and search terms and then picked studies which seem to confirm our bias.

The source for your link is the same article being discussed here. But given how simple their light setup is, they could easily have added a control group.
